Please let us know what you think of the Klebfest. Sand and clean all the surfaces. It is quite runny when it comes out of the tube, so will spread to create a thin uniform layer, but you have to move fairly fast as it quickly dries. Leave it for ~15 minutes and then get it right first time when you mate the pieces together because it sets immediately on contact. I'm really impressed by it (no connections with the supplier).
The smellier the glue the better it works!
Does it stink?
