CLC ought to offer Interlux Brushing Liquid 333 and strongly recommend its use for anybody purchasing Schooner Gold. I can't imagine anyone using the stuff without a thinner.
On Saturday I applied what I hoped to be the last varnish coat to the hull of my 17LT. I'd used regular Interlux Schooner varnish in the past, but switched to Schooner Gold after the regular stuff was apparently discontinued. I neglected to notice this from the Interlux site:
"Schooner Gold is different. It's not a regular varnish and it's not like Schooner. Developed to apply and perform like a professional varnish, Schooner Gold has a VERY high viscosity, giving it a very thick appearance in the can."
Indeed. After using Schooner Gold without any thinner, I will definitely need to apply at least one more coat. I fought with it for three hours. It goes on thick and does not self-level like regular Schooner. My foam brushes skittered across it when I was tipping. I've got sags. And I used a lot. There was no other way.
It's cool; my boat is going to be fine. But it will cost a little and take some extra work.
Unless my experience is unusual, nobody should expect to use this product straight out of the can.
I only hope I choose a good ratio when I thin the stuff for the next coat.
