As the popularity of Plasti Dip grows I figured this would be a good and short how too for its removal. I applied plasti dip late last summer for a track day and decided to leave it on through winter as protection for my wheels from salt sand and road grime. It was very effective in not letting anything harm the wheel but it was time for me to remove it. after several different approaches (and internet searches) I found that the best approach (for wheels at least) was to remove as much as possible via pealing it from the rim by hand. I did this and basically was left with the areas between the spokes on my 135's and the back of the wheel which proved difficult, time consuming and tedious to remove. enter good ole water displacement 40. Wd-40 will "melt" the plasti dip and allow you to use a pressure washer to remove what is left. So I took the wheels off the car and hauled them to a local car wash. I found that soaking the wheel in a very heavy application of wd-40 at letting them sit for about 5 minutes yielded the best results. The WD-40 did its job and the pressure washer made short work the rest. I spent a lot of time making sure that there was no residual wd-40 left on the wheels and then inspected them for any adverse effects to the clear coat or paint and there were none. Hope this helps someone who was in my shoes. I know it would have saved me a butt load of time if I would have just done it this way in the first place.
