have access to a steam jenny? if you had a real steam cleaner, with high pressure, i bet it would peel off, in sheets.



Depends on type of liner and prep work done. The professional shop stuff should not come off at all, that's what you paid for.
The DIY stuff and a lazy azz who slathered on a gallon, maybe.
Like Scratch said, possibly identify what you have and recoat it.
