In our new house, I bought Valspar Signature paint from Lowe's to paint the entire interior, but ended up hiring professional painters to do the job. Nice, honest guys, who very timidly pulled me aside after putting on 2 coats of the Valspar and asked if I'd be offended if they went and bought Sherwin Williams ProMar 200 to finish the job because they weren't impressed with the Valspar (and, further to their credit, they refused to let me pay for the SW paint).
So, I'm a pretty discerning guy, and I can't tell the difference. I have both the Valspar and the ProMar, and after painting some walls myself with them, as far as I can tell, they're the same.
I've tried SW Cashmere and Proclassic, in the past, and just couldn't see what was special. Proclassic was hard to use.
I want to be the kind of snob who pays twice the price and goes out of the way to buy fancy professional paint, but I just don't see it. This seems to be reflected in the reviews of SW products on their website, which all seem very negative.
Can someone tell me: "Buy a gallon of [xyz] and you'll see why the pros only use..."?
Or, at least: "Yeah, if you're paying for it with your own money, Valspar/Behr is the better value"?
