I'm just a beginner at this but so far I've found Envirotex Lite goes on really well and comes out great. You have to spin it though. I use the drying motor on my rod wrapper to do it.
The trouble with e-texing plugs is that while a person normaly makes one rod at a time and only need one spinner , making plugs required more spinners unless you only spin 1 plug a day . I now have 7 .
I'll have to build me one of those Ferris wheel style dryers Like Jig man has.
Chumbucket also had a pretty cool drying system that looked like a Train.
