It was time to try this myself. I have two sets of wheels for my car and the winter ones were horrible and stock looking. The finish was pitted and marked from brake dust and neglect. So I wanted to do something about it. I bought a kit to do 4 wheels. I washed the wheels twice, then wiped them down thoroughly with rubbing alcohol. Next I just laid on light coat after light coat of Plastidip allowing each to dry for a hour or better. I also hear that the thicker you lay it on, the easier it comes off when it's time. But you have to get that thickness one thin layer at a time.
Here's what I started with. They don't look too bad, but trust me, they are ugly. Notice the finish flaking off near the valve stem.
I did a couple light coats on the inside as I didn't want to see the aluminum color from the outside. But this scared me as I used a whole can on only a couple of light coats! Only three more cans left!
I flipped them over and stuffed index cards between the tire and the wheel to keep the paint off the wheel (although it would just peel off). Many many coats later, I ended up with this. I even had to make a couple more passes on the inner surfaces of the spokes as it's hard to get in there laying flat.
I learned that I am not quite sure that 4 cans is adequate for (4) 16" wheels if you are doing the inside. Index cards worked great. And my poor index finger was not up to the task of spraying for that long!! I am excited to
them on the car and see the difference. The biggest draw back is this kit cost me close to $70 and are only online from what I have seen. Where in the states, I could run down to the local hardware store and buy 4 cans at less than $6 ea. This stuff is pretty cool. On these wheels, I could care less if it peels off easily or not, but I would like to practice a little on something else before I make the play to paint my wife's 20" X5 wheels...
I would like to try to put a clear-bra on my car with the stuff and see how it holds too.
