The osma adhesive is for 'solvent weld' pipe and fittings and works by being VERY volatile and melting the plastics (smells awful) - I'm 99% certain it wouldn't melt the GRP, and therefore wouldn't create a bond with the insert.

I wasn't looking for the ultimate seal with the plastic, very few things do that, but Tiger Seal will support it sufficiently. I'll check out Stixall- interesting name. Yes, Osma is a solvent and wouldn't work on GRP. I might try moulding some GRP pipe myself. It will make it worthwhile mixing up enough resin for that along with other small jobs that need it.
