Posted some pics on this site when I had done it...
Dead impressed with the results - never really done anything like this before. The best advice is to "Just take your time". If it goes wrong, just rub it down a little again.
Wish I had taken before & after photos the rims were in a dreadful state. To give an idea i had to replace 2 tyres because of wall damage...
Make sure all the tyre is masked. Found really thin plastic sheeting to be the best. You can get LOADS of it for 99p from Wilkinsons, it is used to cover stuff when you decorate etc.
Paint is from Halfords. Acrylic wheel primer, paint & lacquer. The best/better primer has a filler in it. Not too sure what it is called but you will see it in there. One can of each is supposed to do 4 rims, but I gave it more coats and used 2 tins of each. I did paint both sides of the rim.
First I used the acidic wonder wheel cleaner, both inside and out first. Any kerbing was easily removed with a dremmil then the faces were electric sanded with fine grit, followed by wet & dry. Bit of wet and dry between primer coats. The primer shows up the imperfections.
I also used a tac cloth between coats.
Should be easier this time as I have wheels on the car, I had to use the jack and the spare while I did two rims at a time. Not a good idea.
This winter has not affected the finish at all. Not bad for aerosol kit, had my doubts that it would last. But no point spending £200+ on some cr@p replica rims.
Plan on doing the same again with the new rims I have on order. Should be much easier as these have next to no damage, I just don't like the diamond CD look finish...
