I spot sprayed epoxy on the bottom of the rear bumper cover where the stone chips were on my GTO last spring and then I base cleared the whole thing. Basically last spring I sanded it with 400 grit and did some epoxy work on the bottom. Then it was was shot with standox base and Euro clear last spring. The car has sat in pieces all summer, the bumper fell off my cart last week and did enough damage I decided to sandblast it last weekend to strip it bare. I was very surprised that the base clear blew off the epoxy very easy and held much tighter to the sanded clearcoat. I'm sure it never would have been a problem but I am very surprised as I thought the adhesion would at least match the sanded clearcoat. I was wondering if anyone else has witnessed this as I thought using epoxy as sealer has the best topcoat adhesion.
No announcement yet.
Top coat adhesion to Epoxy primer?
