Use boiled linseed, as Roberts suggested. If you want a slightly hotter mix, substitute some VM&P Naptha for the mineral spirits. I always have at least a little turps in my mix, because the smell makes me think Im doing a better job.
Also, be careful which spar var you use. The low VOC enviro friendly products are mostly crap. Example: McCloskey Spar Var in the brown can used to be my favorite, but when they switched to the new formulation in the green can, I had to stop using it. Would not polymerize properly.
