The additive kits seem to be a soldering iron with a tube to feed the plastic through, I was thinking of doing something similar to when I weld aluminium, put some sort of backing plate in then do an additive weld.
I've always used glues on bumper repairs which can be hit and miss. I've been looking at this myself as well as the heated wire which is great for getting some strength back in.
Watching.
Watching the first series of the Witcher again as the new season is due soon. This will be the third time I've started at the beginning again and I still don't bloody understand it.
