I'm contemplating similar questions. I happened to have a spare tire/wheel hanging around in the garage that goes with my set of PS engineering wheels. I am also curious about platidip, so I figure I can experiment with this wheel. Just the other day I plopped down my $6 for a can of black PlastiDip at Home Depot and got started. I applied 5 coats (not too heavy) waiting 15-20 minutes between coats with the fan on them. Application was relatively easy and I didn't experience any runs. I was surprised how much I like the look! Just the right amount of gloss and good coverage.
I'm going to let it sit in my garage over the winter and then possibly do some "testing" with it in the spring to see how durable it is with various possible contamination I will subject it to. I'm also curious how difficult it will be to remove. I think the trick is the more coats you apply the easier it will be to remove. If it removes easily enough with some finger nail plucking and my pressure washer I think this will be a good way to experiment with different looks for your wheels for very little money.
