hey , I was just looking around and saw this post. you shouldn't use "rubbing alchol here part of the wiki definition: Isopropyl rubbing alcohol USP
/B.P.
contains 68–99% of isopropanol
(isopropyl alcohol) by volume, the remainder consisting of water, with or without colour additives, suitable stabilisers, and perfume oils.
the alcohol is the problem its the other crap that doesn't mix witk th epoxy. also another good epoxy thinner is acetone but i. the small amouts you would use on a plug use a eyedroper to add also testor does work used in rod production in a couple different ways.
