Re: crack fix - fiberglass

I'd go with door #2.

A 4" angle grinder ($12 from Harbor Freight or Bargain Supply) will make
quick work of the grinding. Sneak up on it. It cuts quick. Get to the
clean solid stuff.

Fill the vee with epoxy thickened with fiberglass particles and
thixotropicized (I don't know the structure you're patching, so this is the
best strength stuff.) West #403 plus #406 (colloidal silica) or
equivalents.

One or two layers of glass over the fix -- slather them with epoxy thickened
with #406 and then cover with vinyl to save a lot of fairing and sanding.
Force the air bubbles out the side with your fingers.

When cured, wash, sand to roughen, then spray with Rustoleum primer followed
by Rustoleum white paint.

Fix the beds on your trailer so it doesn't crack again.
