re: preval sprayers, I don't believe they will spray the Epoxy without thinning. If the purpose here is three protective coats for maximum moisture protection, then thinning is counter productive to material build. Where brushing/rolling is rather unconventional, given the product will need blocking down the road, any minor defects are not that much an issue. For someone not wishing to spray for whatever reason, rolling gives you good coverage, no overspray issues to deal with, and yet gives you a quality product that is about the best paint substrate you could ask for.

I have read (grain of salt thing) that Eastwood and Summit are reselling Kirker paints. I can't speak to the quality of their products, but if you can get the shipping and discount deals that these guys pass out on occasion, it would seem to make the Kirker paints more appealing. Not sure if you can get a better deal by cutting out the middle man, I think Kirker uses them as a distribution network in much the same way RMD uses Baileigh Industrial.
