Are you sure its pastidip vs powdercoating?
Plastidip will barely hold up to anything -- the whole idea is that it sticks to itself more than the underlying material.
Any solvent or abrasian shouold make short work of it.
if its powdercoating, the two solutions are heat (bad idea b/c of warpage and messing up the underlying material properties) OR media blasting (what you should do).
I know for sure its plastidip because I am friends with the previous owner. I read elsewhere that the WD40 trick would work. I have also read that bug, sap, and tar remover would work. It seems like it is baked on. I am going to try spraying a thick coat over it and then peel it off as a last resort. I was told that the thicker it is, the easier it is to peel off. I apparently get my information in the wrong places but these are my new ideas.
Once plastidip has been on there a while, it is a royal PITA to get it off! I had sprayed my whole car with it as a temporary measure to cover fading paint, and 2 years later when I was ready to paint it, I was cursing myself for doing it in the first place. Ultimately paint thinner was the only thing that worked, but even that took some time. I ended up having to scrub it off with rags soaked in paint thinner, as that was the only thing that worked. I tried peeling it by hand, wd40, the official dip dissolver, mineral spirits, power washer, goo-gone, hell I even tried hitting it with 180 grit sandpaper on a DA, and all that did was immediately clog the paper up.
My experiences with Plastidip doesn’t melt into itself like lacquer paint coats, so you won’t be making it thicker respraying so much as you’d be adding another layer to the layer that doesn’t want to budge.
As Mike said, it gets stronger with time, and on wheels(due to the proximity of the brakes) and engine components the heat does harden it with time preventing the “peel off” gimmick it promises.
What Matt said is good advice. The factory paint is going to be stronger than anything that sprays out of a rattle can. Don't be afraid to go at it hard. I have even used brake cleaner to take off stubborn stains
