I like SW- A100 oil the same as BM fresh start oil
I like Zinsser 1.2.3 latex primer and cover stain oil for small areas
I like SW prep-rite products a lot, they've never done me wrong
I like SW Duration for exterior bodies, and SW superpaint for trim
I like Pittsburgh latex finish and Pro-Classic Latex for doors
I like BM regal for finish on interior walls
I'm getting far away from oil based finish paints, but havent found a latex primer that is nearly as good as oil primer, especially for hard woods, bleeding, tannin, knots, etc
Hope this helps, all paint is expensive, so pick whichever gives you a slightly less cost but superior quality...good luck with that HUGE crew
