Re: I like my VW mags. Can i sand and paint them? Comments/Ideas... (mk1gti girl)
Ok, I have avoided responding to this thread cuz I wanted to see what y'all were going to say.
If you paint alloy wheels with spray bomb over bare alloy they will only last a few months maybe a year before they start corroding the paint off and chipping like crazy. Aluminum gives up it's atoms to corrosion very easily and will turn white with powder. It has to be media blasted and powercoated to have the paint last. If you strip the rims chemically, sand the poop outta them and clean them like crazy, them use that green zinc chromate primer(the only way to spray on alloy) they will look great for awhile, maybe a couple years but they will still not be as chip resistant as powder coating. Powder coating is cheap, including blasting, around $150 for a set of wheels if you use a regular run color like black or silver. If you insist on doing them yourself, the faster you do it the less long it will last. You have to spend hours on the prep, and it's still short term.
For bunpers the body shops often use SEM Bumper Black and Trim Black, it is the best for adhesion. Did the grill on my 80 Scirocco 6 years ago and you still cannot tell that it was painted. The Bumper Black I haven't tried but the cheap stuff will chip or peal off after a while and it goes on too thick looking more like rock guard. Makes a horrible mesh of your bumpers and flares, use the best.
For vinyl, I used SEM vinyl paint(spray can). I sprayed a set of metallic blue inside door cards from a 78 Scirocco that were used in my 80 for 6 years. The paint was perfect, flawless and extremely easy to apply. They stayed perfect until someone spilled metallic silver from one of those marker pens on it and that wouldn't come off. No biggy, just pull the card and respray. Make sure you clean really well. I took them out of the car yesterday after 6 years of use and the paint is excellent, no chips. I also did the tan colored rear panels and they are the same. This stuff is too thin to chip and very flexible.
SEM stuff is available from auto supply stores and suppliers for autobody shops. There are atleast 10 places in the Vancouver area that carry it. It is not expensive.
