What are you talking about??
Refilable
DI cartridges?
I have been filling my own cartridges with resin from AWI and the resin depot. Both have great resin.
AWI sells the refill kits also. Saves some money.
I went in on buy with a guy for 1 cubic yard of resin at the resin depot and it is some good stuff. A lot cheaper then buying them already filled, no need for the color change resin with a
TDS so you can save even more.
