Ah, ok. That's why you do it professionally and I don't!

So think its important that the paste/filler used in this application maintains at least some flexibility.

Silica and Gell mix is usually just a filler and is like a dust the you mix with Gell. It's only as strong as the Gell, we don't need to put it in really as the mat that we've put in will more than do the job, it just there to soften the corners and make consolidating it a bit easier

This bit is important as mat on its own isn't waterproof.
Should go back to another asking why some boats are dearer than others. I would bet that 70% of ribs aren't Gell washed below deck

Same thing, we used to save all the old Gell bits in a big drum and use it, don't matter what colour it is, it's only used to seal the matt

do you use a polyester resin or epoxy resin to do the rebuild work?
