ahhh, yes.......
that goes back many moons to when I built their RAU 1X whaler, and it was supplied with a small kit of Stablit express............
My whaler took many hard knocks in its life[ including my mates ramming it regularly on the pond for what it represented, lol] and dropping it from the kitchen table onto a stone floor whilst building her, and the timber frame and ABS never parted once at any point........was a brilliant adhesive, and I would also recommend it..........next best thing to welding, so long as both surfaces are roughened with 240 paper to give a key as recommended by the manufacturer.
