I had done mine about a month after getting the car, around march. My reasoning behind it was the wheels were in surprisingly good shape and I wanted to protect them from any curb rash or rock chips, and also figured I could spice things up with a little color. I sprayed em vintage gold (no base coat) with 1 coat of glossifier for a satin finish. It turned out a lot better than I had expected it to.
The stuff was soooooo hard to keep clean tho, especially in the summer when it was hot. The plasti dip gets a little sticky in the heat and it makes the brake dust a massive pain to remove. You can indeed blast it with a pressure washer to remove the worst of it, but youll still have to wipe them down real good if you want them to look really clean. Most of the time I just ended up letting them look a little dingy as I got tired of it. Might not be as big an issue with a darker color I dunno.
In september I replaced the wheels with some vmr v710s. The plasti dip had held up well with no tears or abrasions anywhere. I only got around to trying to peel the dip off a week or two ago and I barely got thru one wheel before saying **** it. While it did indeed protect the finish there are so many little nooks and crannies that its really problematic getting all the dip off. In the official plastidip videos the wheels they peel are always simple spoke patterns with lots of space, but the //M spokes are thin and have lots of tight spaces between the double spokes. I had to go at it with a heat gun and a plastic spatula and even then it was difficult. This was with bare wheels too, I cant imagine how bad it wouldve been with tires mounted and the wheels on the car.
Would I recommend it? Yes, but only as a short-medium term thing. If you want to try out different colors before powder coating, protect your wheels during winter, or plan on getting a new set within 6 months then by all means plastidip them. But as a permanent or semi-permanent thing it just doesnt seem like it would be worth it.
