I have a deal where a guy bought way to much material and resin and is going to be selling it at half of retail cost. He used it to build a wooden boat

He has a couple 5 gal pails of System 3 G2

can the G2 only be used for bonding and coating wood or can it be used as a resin for fiberglass for tabbing and building laminates

Yes, except when coating wood it can peel from the wood expanding/contracting. unless it's plywood Only thing you need to very aware o; epoxy doesn't not hold up to sunlight

From the literature it's only recommended for gluing/laminating wood pieces, beams, etc, not for laminating cloth. I suspect it's going to be rather too viscous for wetting out fabric and wouldn't work well for that kind of project..

Recommended Uses:
Marine - Ideal for stitch-and-glue, sheet plywood, strip planking and cold molding. Perfect for laminating stems, ribs and deck beams. Bonds marine woods to fiberglass, ferro cement and steel vessels.
Construction - Use for making strong structural joints and laminations. G-2 is found in laminated wood beams, doors, windows, millwork, furniture, cabinets, window frames, archery bows and wooden tools.
No mention of use with any sort of fabrics/cloth/ of any sort.

yes it tends to yellow in sunlight thats why i coat it. the only thing that is getting covered in epoxy that is wood is the interior tables and counter top, (butcher block) and the deck support beam

edit and interior trim

..... I wonder if i should call system three
Or at least talk to a distributor.. that would be best - and better than relying on internet forum 'experts' ;)...

Tabbing with cloth is essentially the same as "stich and glue" G2 would most like work ok for that. It's not going to as be good for clear coating wood I've used System 3 on canoe builds as well as west system. you do want to tab the glass to rough surfaces. smooth gel coat will bond but not as good as rough.

Over the years I've grown away from the thinking that epoxy coated table tops are "better" Now I just use multiple coats of varnish or urethane and get very nice results.

I think G2 is the old Burnaby based Industrial Formulators G2 - System 3 bought them out but continued their resin formulations like G2 and Cold Cure.

G2 was fairly viscous and wouldn't work all that well with fabric laminating. It's a great resin for other uses like laminating wood, thickening with various fillers etc.

It's been a few years but IIRC it had a good open time - like 40 minutes.

Wow. That's a long time. It would take me forever to get all the fillets right on my dinghy build. That would have been useful to have some that sets off fast, and some slooow. OTOH, Abuse, you probably won't need more than a gallon to do the fillets and glass on a small dinghy, depending on how thick the sheething is. So, maybe just get stuff that would be useful for both.
