I apologize for seeking info that I know I've seen on the Forum (but after many searches cannot find). Is it essential that one use Interlux's proprietary "333" thinner w/ Schooner or will another product suffice? If so, which products?
Go to "Varnishing Struggles" on the Forum. Joey Schott adds a good post. I am about to begin varnishing, and this query has me a little daunted. And the answer. Joey says ditch the 333.
