    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

    For the screw holes and a few gelcoat cracks I would use flow coat

    Hi Tackle, thanks for the reply mate.

    I chose to use resin with the powder so I can make it thick like a putty as it needs to be shaped a bit as the holes are on a sharp bend on some.

    Wally I keep forgetting about this stuff I first used it over 20 years ago I think it was when it first came out absolutely magic stuff but not cheap ......
    Edit
    I have noticed they have many different types for different jobs now makes it even better
