Good point. Unless you strip the paint before you glue, I guess the bond is only as strong as that of the paint to the clam.Sure. They installed Marius's with adhesive and it stayed on perfectly.
Well until he hit 90 mph and then it ripped off taking the paint off the clam and he of course had to drive over it and now it is in pieces bouncing down the highway for other cars to swerve and miss
Use the dang bolts, you can't see them anyway
