Well, I gave the Facelift resin a test this time round. I usually need to change one of my canisters once every 4 to 5 week. (Resin only system using 2 canisters on rotation)
Tulsion resin never goes past 4 weeks, Unger resin impressed me with just over 5 weeks and Facelift? Well......
It lasted one week. Complete pants.
I've tested these so you don't have to. So that's it's only value to me. Never again.
