Patchwork!

I have been told that polyester fibreglass is not so great for spider cracks and repair work. I uses long strand molecules that don't grip and bond that well. Epoxy is what I was told? Any thoughts, folks??

The cracks I think your talking about is in the gel-coat of the fiberglass I assume.
I worked just with epoxy/resin fiberglass while building canoes and know for a fact, if the area is clean of oils and wax this stuff will stick.
I used what is known as a fillet with is ground glass fibers mixed with the epoxy/resin mixture and filled and smoothed out many of little imperfections.
Spilled a dime size dollop on the cement basement floor and 25 years later it is still there in a high trafic area

So I think I have it... Premium epoxy (eg. West Marine) and micro-balloons. I was originally going to use marine gelled resin, so it would not creep down while curing. Must get my ducks in a row when I pick it up from the widow in April. Should fit in my garage without resorting to temp 8" wheels. Unit has original style 13" tires. New sizes are higher profile, I believe...Cheers!

if it's just spider crack in the gel-coat and not a structural repair use bondo. You don't say if you are going to repaint. If you are not, that is a different fix.

I plan to repaint both upper and lower shell pieces, esp. the bottom.
