Hi Pat,
Thanks for sharing. I like that mixing nozzle.
(Thats enough to sell me)
Looking at the physical properties between pro-set
and the standard west epoxy, there appears to be
little reason to go with the pro-set? So I take it
that all the advantages are in the no sagging and
the easy mixing?
Also searching the internet I found this stuff
pretty hard to find. Looks like its ready available
in the UK. Care to share a good source for this?
Thanks,
Christian/USA015
