I guess your mixture would work well with red cedar, what mix rate of BLO, Mineral Spirits and oil based poly (I guess Helmsman Spar Urethane would work) do you use. I just don't like the Spar by itself on red cedar.
3 equal parts. I just happened to have Minwax satin finish oil based poly so that's what I used.
Some people use the 3-2-1 ratio (3 parts mineral spirits - 2 parts Poly - 1 part BLO) and I may try that next time. Like this guy...
I sanded each one of my coats in and then rubbed them off like he did except I used steel wool as the applicator.
Honestly you could just leave out the poly all together and go 50/50 BLO and Mineral Spirits and that gives a nice finish too. I done several gun stocks that way and they turned out beautiful. Not sure how it would hold up to glasses and cups being set on it though.
