Gluing fenders on adventures

[kayentaskier]

regarding the fender mounting ... I 'm probably this guy:

 

I've heard an anecdote about road use in Utah, possibly caused by HUGE temperature swings

 

my fiberglass front right fender blew off at about 65-70 mph on a 70 degree Summer day . The car was built by Josh Robbins, so I'm pretty sure the fender was glued properly. The best guess was the glue could not stand up the the temperature swings between 110 degrees is Summer to below freezing in Winter (my garage does not HVAC). The fenders are now screwed on.

That sounds exactly like what Josh relayed.  How did you screw them on?  I think he said bolts through the top into the stay, with stainless + neoprene washers?

 

I'm planning to use 3M 5200, which is generally considered "don't use this unless you never ever want to remove it".   The fast cure version only comes in white tho, so I'll either top it with slower-curing black, or (and?) will undercoat the fender.  It's already painted, acetone took up some of the paint when I was prepping for the adhesion.
