Wonder if any GRP experts on the forum, could make some suggestions as to
the best way to join together 2 mouldings, which when bonded will form a 50
litre watertank?

There is a 10mm wide flange on each of the mouldings, and clamping them
together would be no problem. Have already had epoxy suggested, and also
polyester resin with colliodal silica to thicken it.

Many thanks for any advice, would be nice to hear what any GRP experts might
have to say on this one.

TIA

Epoxy should be your choice, Thicken it with micro-fibers or make your
own from (very) finely chopped glass. The thickener is a MUST that is
what makes it a glue. Epoxies and resins have no tensile strength by
themselves.

Well, first of all polyester is a laminating resin not an adhesive so that
idea should be killed off very quickly and permanently.

Epoxy is a possible choice but with only a 10mm flange you don't have a lot
of bonding surface and there is not a lot of room for backup fasteners.
There are several other approaches I might suggest but it would be best to
know what the moldings are made of. For example fiberglass would require a
completely different method than PVC or polyethylene.
