Screws have worked their way lose. Re-drill Screw Holes? Fill with Resin compound?

[AMetzger]

Some of the screws that hold the windshield to the dash have worked their way lose. I can screw them tight again, but over a few weeks, they'll work their way loose again and the windshield will rattle a bit. I know I could replace those loose screws with bigger screws (I would also have to drill out the screw holes on the aluminum on the underside of the window), but I would rather not use that solution.

Is there a way to fill the current screw holes with a fiberglass resin compound? Then, I would re-drill the screw holes and put the original screws back in. Specifically, what resin compound might I use? (I've looked, but cannot find what exactly might work the best). Thanks.

If the screws are still holding I would put some 3-M 5200 in the hole then tighten them a little past snug and let it set for several days.

I usually just put some epoxy in the hole to close it up a bit and then put the screw back in. Fiberglass and screws do not get along very well. Somebody should let the boat manufacturers know that . . .

can we see some pics of what you are working with?
normally the attachments for a windsheild are a bolt with a nylock washer.....they donr come loose !

My windshield has bolts that extend down from the aluminum channel and have locking nuts on the bottom (and a dab of 5200) so they do not come loose.

Some windshields use sheet metal screws which tend to shatter the fiberglass........ you can install them into wet 2 part epoxy but eventually they could work loose........ can you replace the screws with a stainless nut bolt fastener????? That would be better.
