Re: My First Fiberglass Repair

This place is great - good advice here.

Biaxial cloth is probably a good idea with the curves. Respirator and sheeting off - definitely. Only thing I would add is the importance of acetone, generally before as well as after sanding/cutting, to make sure that you don't drive contaminants into the surface you are preparing.

Also give the wood a light sand and thorough acetone wash (respirator!)

Finally - this will sound odd - the viscosity of epoxy changes dramatically with temperature. I did a project which started in winter, when the epoxy was like molasses, and ended in summer, when it was like water. You want the epoxy to penetrate wood/cracks/cloth, and so may need to *slightly* warm it to reduce viscosity. Clearly this also accelerated hardening, but with a slow hardener you should be fine.

Enjoy! Fixing fiberglass is easy - and fun!
