I hate to say it... Plasti dip isn't that easily removable. It's a bitch to get off. Not worth the effort in my mind. I did it once and it sucked.
Look up the poor guy that dipped his car on the Toronto Subaru Club. It's not going well for him. It's a good product for certain areas.
Look up a powder coater in Cambridge Ontario if you are needing different colours/protection/fixing. Stripping technologies. Great guy, prices are great too.
