My rotisserie mounting bracket bolts to the bumper brackets that go on the rear of my Mustang. I sprayed these in Epoxy last Saturday. Obviously these get bolted up tight, how long do I need to wait? Very old picture, but you can see where it mounts. I'm mounting it for a final spray of the interior (easier done on it's side standing in the door opening). Car is blocked and the exterior ready be sanded and sealed so I really don't want to goof up the epoxy in the bolt on area.
