Fiberglass repairs

[Skools Out]

yes alot of boat company's use bondo to create chines on the hulls in the molds then glass over it. you can mix you bondo in to resin with hardner and that will make your bondo hard as a rock and water proof cause raw bondo will soak up moisture.

Skool,
Help me understand. Are you saying mix bondo and its hardner then add the mixed bondo to epoxy resin and hardener?

no not epoxy and bondo mix your poky resin with hardner and then add some bondo to it to thicken and it is like micro ballons but harder. you can add hardner to your bondo first but will set up fast or just put a little extra hardner to your poly / boat yard resin.

This will give you a good idea the difference choices of addatives you have for various resins.

Bondo is cheap and not very strong. If you're going to use it . . . do what skools said . . . mix it with some Polyester resin.

If you want to mud that gap milled fibers, cabosil, and epoxy mix will give you the strongest goop. Make sure everything is dry and that you prep and clean the surfaces. Tape off the area to keep the mess contained and pull of the tape when the repair is still tacky.

Warner - it's a big no no to use polyester over epoxy . . . and you can't mix the two resins.
