garfield28 Posted June 28, 2020 Share Posted June 28, 2020 Hi all, I'm trying to fix a few things on my fibreglass boat before putting it up for sale. I have a few small screw holes and a few gelcoat cracks that I've grooved out to fill, and I'm just wondering if I should use an epoxy or a polyester resin? I bought some epiglass HT450 which is like cabisol and I planned to mix it with resin to thicken it up like a putty to fill in the holes and cracks. I mixed a batch of the epiglass 450 with some polyester resin that I have here and it doesn't seem to be going off and hardening at all. I also need to do a small bit of fibreglassing too, to fix a molded seat so if I can use whichever resin to do both that would be great. Appreciate any advice. Thanks Geoff Link to comment Share on other sites More sharing options...

Thanks Geoff Could you just use flowcoat or are the repairs needing more than that. Just a thought 1 Link to comment Share on other sites More sharing options...
garfield28 Posted June 28, 2020 Author Share Posted June 28, 2020 (edited) Hi mate, thanks for the reply. I guess I could have for some, but a few of the holes are on like a sharp bend and I wanted to make the resin like a putty so I could shape it.

garfield28 Posted June 28, 2020 Author Share Posted June 28, 2020 Mate didn't know there was such a thing. Is it ok for marine applications ? If so could you please PM me the name of one and where I can buy it. Thanks Link to comment Share on other sites More sharing options...
