Frank, thanks for that! Yes, as you said the quart is a bit more than what I had in mind. I'll try and see if there is any way of buying less.
Cami, I saw that cabcoatings are developing something (saw solarfallbaits's video on youtube) but honestly it is hard to navigate around their website since it is only in finnish and also as you said, as far as I know they only sell in Finland. They would have been perfect otherwise
