I was a product manager for Wolseley for many years. I remember when these pp systems first arrived in the UK, the first time I saw it there was a guy from a German outfit called Polymelt.
The guy spent several minutes trying but failing to give us a presentation on how to make joints, it was completely embarrassing.
We eventually conducted a trial with it but they lacked the resources to make it happen and we returned it.
MLCP is the way to go, bu I’ve not seen it here.
