I bought a performance package six piston caliper to have powder coated. When trying to get the dust boots off there is rubber left all around the opening. Every video and tutorial shows everything just pull right off with nothing left. I’m not sure if these got melted on but I’ve worked with a pick and a razor and there’s still rubber left with five more pistons to go. Anyone have this happen to them and how did you fix it? First pic is boot and inner seal in place, second is boot with no inner seal, third is both removed with rubber left overs stuck all around.
