Cobez is on the money, I only done it to see if I really wanted to powder coat my wheels, with next no prep and being removable I haven't committed to sanding and ruining my wheels, with almost no damage after 12 months and being happy with the result I'm going to leave it as is, cost vs ease of use is great, besides if the surface was to get damaged what's the worst case? Another $20 for a touch up can that will last for years at this rate!
Not to mention the DIY ability of this stuff is awsome. anyone can use it to good effect and the possibilities are endless, I even used it to seal up my trailer wiring where I couldn't use heat shrink on the three way junction (over the tape).
