Because I'm a sucker for punishment I bought another E90 but this one came with a less than perfect body and I'm keen to fix it.

This one isn't too deep and it looks like somebody has just hit it with a can of genetic silver spray paint. I'm assuming I'll sand the clear and colour and then fix with some filler?

I was going to try and pull these out with my puller but that bottom crease is hard! There is access behind but it's really tight. Might be able to get a PDR style pry tool behind.

Would love some advice.

Thanks guys

You take it to a crash shop and pay the money.....

don't know if you saw, but he bought a BMW, wouldn't be worth it to fix professionally.

I reckon do the same as Marty did on Kel's march super turbo; just get a vaguely similar colour spray can and shoot in the general direction

Thanks all :rolleyes:

New boot definitely an option @The Bogan - about $300 for a good'un.

Its that guard though. Surely I can make it look better without taking it to 'the man'.

I agree with the new 2nd hand boot option. You could as you said in the first post sand/fill the guard. It's going to be tricky to get a satisfactory finish diy painting it. Maybe just get a quote from a shop to just repair that part and see if it's economical enough. If not, just sand/fill/smooth. Get a can of paint mixed up and watch plenty of YouTube vids on how to to a blend in.

Doesn't need to be perfect. Its the 2nd family car after all and, despite my emotions, gets beat up a bit. :(

I was thinking a can of body colour and clear, sand, fill, smooth as you said and do a soft-edge spray job on it. Wouldn't be worse than it is now.

Sounds like a plan.

If you're going to do the repair, there isn't any reason why you can't get it looking pretty much factory. 

In no particular order - 

* Get a good colour match paint. I've had really good experiences with VG Auto Paints: Automotive Paint Supplies.

* Use a proper 2K clear (it will have a button on the bottom of the can to release the hardener) and good quality primer. 

* Take the time required to prep/repair the damage. Ensure the filler is 1000% perfect and smooth before painting, eg if the 2 part filler is giving you tiny pin holes when it cures, use a single step filler to fill the pin holes. You can't rush or cheat out this step, it takes as long as it takes. 

* Don't try and blend the clear coat. You could blend the colour, but you might as well use the entire can and colour and clear the entire panel. The 2K clear will only last a few days once activated anyways so at least it will all get used. 

* Have a good respirator. 2K paint isn't friendly. 

* You'll probably have a pretty orange peel y result using rattle cans. Nothing 1000 / 2000 grit sand paper and cutting / buffing compound can't fix. 

It really isn't that much more effort to get the factory result, you're already in there doing the repair, might as well make it perfect.

That's brilliant, thanks @Murray_Calavera

Considering it's the rear quarter, that's a lot to repaint with the rattle can. I'm worried about my results. 😬

I do have an air compressor but spraying has always been something I'm a little worried about.

If I'm spraying outside is it only a respirator I need? I know you need a full suit when in the booth.

Really awesome advice, thanks!

Btw I have previously tried to spray a front bar in my backyard using acrylic and it sucked. Bad.

Thats the thing about painting in general. It sucks the first 200 times, and then you think it sucks the next 1000 times, but other people say "Nah its actually good!" at that point. There's not much in the way of shortcuts.

Ohh it's the rear quarter :( I was thinking it was a front guard....

Can you upload another photo showing the entire panel? 

What we need are natural body lines/panel gaps where you can stop spraying the clear. Ideally a panel gap. This is because blending the clear coat is not an option. 

I'll post an example photo. Say the damage is the red X, then I would colour over the damage and re-clear the entire area in yellow using the body lines to hide the blend point. 

If I'm spraying 2K, I wear a respirator, paint suit and gloves. A disposable paint suit is only around $30 so I don't see any reason not to use one. 

I have a feeling your air compressor might not be up to the task, you really want something at least this size to feed a spray gun - https://sydneytools.com.au/product/chicago-hush150-silenced-150l-air-compressor

If your a bit worried about working on the BMW straight up, you could go to your local wreckers and pick up a cheap panel and use it to practice on first. 

Once you're happy with the results you can achieve on the practice panel, you could move over to working on your car.

Thanks again for this help.

Here's the entire panel.

There's a few other scratches and dings in front of the filler but it's all straight behind it. The shadow makes it look a little wonky.

This would be the cheapest way to paint it. Blend the colour over the damage and clear over the red highlighted area. 

What you would do is back-mask using that body line. Here is a good example video of the technique.

Thanks again for this help, hugely appreciated.

Bloody car lost its water pump last night so its in the shop getting that and some rattly wastegates fixed for the next few days. Will formulate a plan of attack for the body when she's back.

budget and/or lazy option - maybe just get those over arch stickers that are body colour coded?

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
