Hey guys, I need a little guidance before taking on my first real project on my second car. I've decided to change out the radio for a unit with an auxilliary input jack and MP3/WMA capability, and figured that while I have the dashboard apart, why not paint it. I'm going to paint the silver center console in this picture a pearlescent white, since the silver paint is flaky around the edges:

The paint I've picked out is Tamiya's TS-45 model paint. It's a small spray can of lacquer paint so it doesn't need any clear coat(if I understand lacquers correctly). My only experience with painting car parts was with spray painting my Riviera's engine cover. I've never painted anything like this and need it to come out looking great. My questions are: am I making a good choice in picking a lacquer model paint(made for plastics), should I use adhesion promoter or anything like that, and a confirmation on my assumption that lacquers don't need a clear coat on top? Thanks a lot in advance guys.

I think you're going to have durability issues with the laquer and hence need to get a can of paint you want made up at an aautomotive paint shop.

Just sayin'.

If lacquer won't hold up well, I could spray it flat black to match the rest of the interior instead, but I love the look of pearl white. I'm limited in that I don't have an air gun and can only use spray cans. Would acryllic or enamel paints have the same issues?

the best thing to do is get a urethane paint at the auto body shop. its way more flexible than the one for models. adhesion promotor is allways a good thing. most important is the prep. clean ,sand,320grit,clean again. adhession promoter and then the color. if you clear coat the end result,the finish will last even longer. PREPARATION IS THE KEY!

I'd make sure to clean the surface very very well before doing anything! I'm wondering though, how would I apply paint that I would have made at an auto body shop? I don't have an airgun, and only have a little air compressor(150psi max) for filling tires. I doubt you can brush this stuff on(never heard of brushes being used on cars).

SEM makes a thousand different colors ready to spray. if they dont have(highly unlikly)the color you want,they can mix any color you want and make a "spray can" for you. no need for a compressor or special equipment to do small jobs. just have to find a good body supply shop that has the machine to make up custom spray cans

I definitely will, but finding what I need from SEM is a bit difficult. I think I've managed to find pearl mix-ins(sorta like that yogurt), but am stumped as to what I mix it into. A white paint? Clear coat? Do I do a white primer and then mix pearls in with clear to spray that on?

why not let the paint shop worry about sourcing the pigments and additives?!?

Got it in this morning, along with the new radio! Each piece was gone over 9 times with the pearl white paint. The primer started to drip a little since I hung up the parts to spray them, but overall it looks pretty good. I used 1500 grit sandpaper to make it nice and smooth to the touch, even though the surface may not look completely smooth if you put your eye right up to it.

Thanks! I'm pleased with the results for my first time doing paintwork like this.

Your Riv was actually what inspired me to do this, after seeing your chameleon dash!
