Hello

Hi, new to the forum. Can anyone help me with some ideas about how to fill old rivet holes in fibreglass where I can not access them from inside to block the back of the holes?

Thank you,
Christopher

I wonder about those patches. Typically, the fiberglass edges around the patch are ground and tapered.

All those areas can be accessed inside the cabinet, at least on mine.

I used JB Weld WaterWeld product to patch small screw holes where I could not get inside. Not sure I would recommend it to others, but it worked. In my case, someone had put a padlock hasp on my door (ouch).
