hey guys,

I had a few scratches on the side of my car, and i was going to touch it up with some touch up paint, and then use a cutting compound to bring it back to level... BUT it turned out a LOT uglier than i expected, and the cutting compound did nothing.

I ended up getting lumps over the places i painted (even though i tried my best to paint it evenly) and whenever i use the cutting compound over the paint, it never looks like it's even getting closer to the paint level of the rest of the car. I've been doing it by hand, because i dont have an orbital polisher, but i spent about an hour on it and the level of the touch up painted parts look the same as when i started using the compound :\

here's a photo of it,

Help please?

did the touch up paint have instructions on it? ive got some scratches on my car and ill be fixing them sometime in the near future - but not if it turns out like that... i thought the touch up paint was like a pen that basically just filled in the scratch?

Look, you're never going to get a perfect result on black using touch up paint; that's just life unfortunately.

I think your expectation and reality are fairly different, you may have to accept that if you want a flawless finish; basically wiping paint on to your car is not going to work.

I also have a black car which someone rather generously keyed down to the undercoat; and it sticks out like dogs balls. I'm just going to repaint the entire panels. I'd rather not, but you are seeing the alternative.

I can only propose an alternative for the future; the reason touch up paint kits are tough is because you are applying with a brush obviously.

In extremely small doses i've been able to hide small scars and inperfections by getting an aerosol made up and piling tape around the scratch; literally with milimeters of spacing trying to leave the gap exactly the same size as the scratch; and spraying the aerosol in one or two quick motions. It's still tricky and difficult and it doesn't look as good.

Your main problem there is the "bubbling" effect where the surface is not smooth... i guess the first step would be to get somebody to try and sand it down flat... i don't know. maybe a pro could do it with a machine sander, maybe he'd do it by hand.

gumflapper, it didn't come with instructions, I got it made up at autobarn

damn I was scared the answer would be a professional job :( i'll try to sand it down with fine grit sandpaper and hopefully it works.

Please be careful wet sanding. You dont want to go too far and break through the clear.

If the paint you applied is still fresh, you could try a more agressive compound to try and remove it and get you back to where you were before.

Try meguiars ultimate compound.

Also, an oribtal polisher will not help you here.

Orbitals + Dual action polishers are not designed for hardcore paint correction such as this (not saying that they are not capable of it though).

They have a counter weight in them to avoid heat generation and prevent clear coat break through. Not as effective as your standard rotary polisher (such as panel shops use to manipulate the clear after spraying - orange peel - etc), but very safe for novice users.

To fix your problem, if you take it to a pro they will need to wet sand it down and then buff with agressive compound and then buff again with polish to restore shine and then wax to seal.

Its stuffed. Burn it with fire.

But seriously, just get it done properly. I think you can use cutting compound/fine grit all you want but that is never going to look good. Point is, you will always know its there- and your eyes will go straight too it all the time.

Get it done professionally, save up for a little while or whatever, and get it done properly. You'll never know it was there. Touch up paint is good for stone chips and the like not stuff like that.

You must of applied way too much. You will have to get it sanded back and resprayed by a shop. What panel is it? If it's the front quarter it's very easy to get one of those hard discs (not sure of the proper name), put it in a drill and take the paint of yourself and then get a color coded spray can from autobarn and spray it your self. It won't look as good as a shop but cheap alternative.

Cutting compound was never going to work, the stuff is essentially used to get rid of orange peel or overspray and polish up an already good paint job. Your only option is to sand it back and go again. If you know how to spray then it's easy, but given you tried touch up paint originally I'm gonna assume you don't.

Do not Wetsand the paintwork! if you cant apply touch up paint correctly chances are you will rub through. As mentioned above take it to a shop and ask them to sand and buff that area.

Have to agree after looking at your pic...

There are other scratches present too.

And ask the painter to make up some extra touch up paint for you > perfect match for the future.

I'm not happy with the "GV1" Pearl Black paint you had made up anyway.

And by the way, your car has been exposed to years of sunlight, rain.... You name it. You never get a colour match off a paint code. Best thing to do is to get the code and petrol flap and take it into a auto body supply store and get it properly matched. Paint fades over time.

Paint fades over time.

Sure does, I remember one of my black R34's when I got it, the paint was a different colour to one of the other panels which had been freshly painted.

I compounded and polished the whole car and the paint matched perfectly after the love.

I just finished rubbing back and respraying my car's guard. Was pretty easy as the guard was off the car. The only thing I stuffed up on was the clear coat as I ran out after 2 coats. I a going to get it buffed and see how it goes. So if you get another spray can and some clear give it a go.

You will never get a perfect finish from a spray can. This is the reason I invested in a $1000 compressor and a $500 spray gun.

That is very true, but it a quick temporary fix until you can get it re-done professionally.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
