Spray painting interior plastics

The E39 has some pretty poor condition plastics with big scratches and fading colour. The problem is that the trim is grey and I've done some research and found a rustoleum colour that matches, but the paint is enamel and is for wood and metal.

I was hoping I could thoroughly clean the parts and use a plastic primer or adhesion promoter and then spray with the enamel. 

I kinda feel like the rough looking, old and scratched trim would look better than a shitty respray. 

Getting good quality interior parts is hard and expensive. These two pieces that hold the chair controls are about $300 delivered if you can find a good pair.

I have too many nightmare memories of a young PranK spraying interior panels and then buying replacements when they turned out terribly.

Thoughts on interior trim spraying?

Your nightmare memories are where my opinion on interior trim spraying lives.

I have seen quite a number of consoles and dashboards and the like painted with (proper) interior vinyl paints, and the colour is always a little offensive, and often likes to rub off on anything that touches it for a long time after it is supposedly dry.

You'd definitely want to have had a good experience with a solution before trying it on something you care about.

I would think that paints that are not intended for interior vinyl will look wrong or not wear well. Wrong if too glossy, not wear well if too satin/matte.

The way I think about it is, it's doomed to fail.

Anything that marred the colored plastic is absolutely going to obliterate any paint finish. And it got scratched or touched or used in the past to get into that state.

People need to start reproducing plastic parts or 3D print replacements that clip in that are colored all the way through and not just coated in something (anything).

100%. There's gotta be better options.

What about hydrodipping? I was looking at it but if the piece is complicated the end result might not be as good, I've seen it recently where if you have a checkered pattern for example and dip it, the area where the plastic bends, those checkered boxes look stretch. Doesn't look terrible but not the best result either. 

Every rattlecan job I've seen has turned out crap (at least on the skylines, they are always peeling and bubbling) but I haven't seen anyone get a proper spray gun and compressor and go at it. In theory they should last a lot longer.

Vinyl wrap is another option (also difficult if there are a lot of complicated sections)

These arn't them, but these are the pieces.

I dont think hydrodipping would work. Also, the plastic is very old and brittle, the trims are out of the car atm getting some mounting holes jb welded.

If the plastic wore, the paint will wear quicker.

Heck, most car manufacturers cant keep the coatings they put on their buttons/trims alive these days for more than 5 years... A cheap paint won't do it!

 

However, you can get away with high quality vynil wrap, primarily in areas that won't cop much abuse. Skip colour matching, and just try and wrap a specific area with an edge in a new colour.

 

PS vynil wrapping is a prick of a job, and I suck at it, even for a small dead flat surface...

Yeah its a good idea, I wonder if I can find some vinyl that will match the colour.

No. Go a different colour, and just trim it at an edge line.

Even manufacturers do different panels different colours etc.

I love where you're going with this!

I am so glad I've been stepping away from the internet more and more so I don't know what "Just Rolled In" is. And no, I'm not googling it, or clicking any links you lot provide.

 

Second, Prank, pretty much, that silver stuff, wrap all of one section in a new colour. I recommend NOT using anything glossy, go for matte or flat colours.

Current work car I'm driving has so many shiney chrome bits and gloss black bits that at certain points of the day I feel it would be easier to drive blind... So much glare in the eyes!

It's innocent.

But sometimes people cannot start their cars or change gears because they have a billion stick-on things getting in the way.

Yeah, i'm not a shiny thing kind of guy but I'd definitely give this a go. Food for thought. Thanks

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.

      They are in fact just nozzles. They are there only to produce a spray pattern and limit flow. The injector itself is what I use to control flow to the 7x nozzles. My old system had no injector and only PWM the pump. This lead to a lot of inconsistencies, and poor atomization at low pressure when the pump was ramping up.
