Gluing to fibreglass
Has anyone any handy hints for how to glue the non-gelcoat side (i.e. the rough side) of two bits of fibreglass together?
I've tried no-nails, and bathroom sealer/adhesive but it's not strong enough adn the parts pull apart easily. I guess the next thing to
try is sikaflex, but I only have a tiny bit to glue and £8 a tube is a tad steep for an 8" long join!
Cheers

Araldite. Or buy yourself some fibreglass mat and resin (dirt cheap stuff)
Make sure its completely dust free (dust loves to get stuck in the rough side of FG). Wash it with meths or similar (not thinners as it can melt the
resin (celly thinners will anyway)

Use some body filler like Isopon or similar make. It works for me
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

F/glass sticks like poo to a blanket when you don't want it to but when you do it will fall off unless you rough up the surface and clean it
with acetone....not too much mind as it will attack it.....sikaflex is good but costs so use a cheapo Halfords f/glass kit

i'll second petes advice, although i tend to use the stuff for filling holes, looks like jam, with strands of fiberglass in it, most motor
factors sell it. Stuck my bonnet scoop on with it, and so far its not flown over my head.

P45 (not the one you get when being fired) is the filler stuff.

Available from Halfwits.

DON'T use araldite. Epoxy does not stick to Polyester. Use a polyester adhesive or a polyurethane adhesive - like epoxy but will stick to
polyester.
Useful tip: If you want to make a mould for use with polyester - make it with Epoxy!

Cheers, I'll try the isopon, I've got a ton of that. Hadn't thought of it as an adhesive.

Don't forget to clean the area well, to get rid of any possible traces of release wax, grease or whatever. Wouldn't hurt to rub it down a
bit with some wet-and-dry or wire wool as well, to give a key (the backside of GRP may be bumpy, but the surface is still quite shiny).
