re: Most Tung oil directions get this wrong

I understand "polymerized tung oil" has chemical driers in it... this is what I use in my work. The alternative...conventional tung oil takes forever to dry. Also, after flooding and giving time for the wood to absorb the oil (a few minutes), the remaining tung oil needs to be wiped off. This leaves no surface film (what we are striving for)  and allows the tung oil absorbed in the wood to harden.
