If you are going to paint them I would recommend professional wheel painters, otherwise it will start to flake off after a few months. That usually costs at least $150 per wheel. I think finding a new set might be easier and better. I do dig the gold though! I wanted to paint my aftermarkets bronze, but I do not want to ruin an old scchool jdm tuner set.
I have done this on my Subaru (Subaru people REALLY love gold wheels..) and it can be done very nicely without a professional paint shop but it takes time and patience.
Most people don't sand, prime and clear coat and that is why home painted wheels often look like total crap.
This is by memory, so take with a grain of salt.
6-10 fine scuffing pads
3 cans white primer
4-5 cans of color
4 cans of automotive clearcoat
A pack of note cards
about 1 day
about a 12 pack or 3 bottles of Chimay
about $90 depending on type of beer.
1. First you jack the car on stands and remove the wheels and clean them with degreaser and dry with a soft towel.
2. Scuff the wheel surface with a fine or medium grit scuffing pad to take on enough of the clear coat for the primer to take. Use note cards stuck in between the tire and the rim to mask the tires for painting.
3. Spray on a primer, (white primer helps the color 'pop') one or two light coats sand the primer lightly with a fine scuffing pad. Wipe off any dust. Wait about 45 minutes for primer to dry.
4. Paint the wheels with your gold paint. Many light coats is better then a few heavy ones. Wheel paint is best but I used walmart gold metallic spray paint with no issues.
5. Sand very lightly with fine paper to get a smooth surface. Check the wheels for an even coat and feel.
6. This is where most wheel paint jobs are screwed up. Spray on the clear coat using even light coats, use about a can per wheel so use as many coats as that provides. The clear coat is what will protect the paint from chipping or scraping off when tires are mounted etc. so don't scimp.
7. Remount wheels after everything is nice and dry
8. Look awesome
