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

Could you just use flowcoat or are the repairs needing more than that.  Just a thought

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.

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
