Long story short last year I glassed in my bulkhead without using a fillet where the deck and bulkhead meet... Well now I know why you're supposed to use the fillet, it's cracked all the way around.
I don't have the time or resources to order the materials to make my own "peanut butter".
So my question is would I be OK using a Bondo style body filler to create a fillet to glass over?

Not really. Bondo will crush like drywall under abuse. I have used Sea Going Epoxy with good results, not the heavy duty. The regular.

I don't think my glass guy used filler when he capped mine. I could be wrong I suppose.

Yeah I don't have time to order any of that right now either. We're going to Parker this weekend. Guess I'll just glass it with some 1708 without a fillet and fix it right when I have time. Thanks!

I think he's referring to the front bulkhead under the deck, not the gunwale. Normally when they cap a hull, it's normally all fiberglass products sometimes using a little filler for minor defects before priming. If it's gel, they won't (or shouldn't) use filler, but rather cabosil or similar.

If there is a Tap Plastics near you, they should stock ground glass or Cabosil.

I wish. I live in the boonies. What's your recipe to make thickened resin fillet?
My plan was polyester resin chopped/milled fiberglass and fumed silica a.k.a. cabosil

Yep, keep adding dry until you get chimney mortar consistency. Add hardener normal, no hot mix.

Could I just use kitty hair to make the fillet?

How would West systems 404 compare to the cabosil?
