I used Interlux Schooner for the first three coats of varnish on the interior of my Peeler. I used it unthinned. It flowed easily and built smoothly. When I ran out of Schooner I ran to the local marine store and grabbed a can of Schooner Gold - not realizing the difference between plain Schooner and Schooner Gold. Well, as many members have found in the past, the Gold proved unbrushable straight from the can and needs to be thinned considerably. Now needing to sand out the brush marks I read that Gold should be thinned with Interlux 333 thinner. Just my luck, every marine outlet in my area is out of Interlux 333. CLC can't sell 333 due to shipping regulations.
My question is can you thin Gold with turpentine or mineral spirits (which I have on hand) or do you absolutely need to use the 333? Now I remember why I usually finish my projects with workboat paint.
