A VERY careful application of just enough heat to soften the adhesive - but not so much as to deform the vinyl - will *usually* allow you to smooth out almost all of the wrinkles. Take the legs off before making any attempt at repair. You may wind up detaching the vinyl artwork from the cabinet in the wrinkled area which is actually a *good* thing; glue it back down with 3M 77 spray adhesive. I spent several hours fixing this on my BBB cabinet and it now looks almost pristine.

Then throw those #$%^&* "leg protectors" away.
