Plastic weldings ok but its never as good as when its welded in the factory..

We have a lot of plastic ducting and fume scrubbers at work that we are allways having patched up and re welded and it never lasts fives minutes.

The bloke from plasticraft uses the same heat gun as pictured, good little bit of kit

I think ull be better off using Araldite and then skimming with filler as this will bond it together better
