I know, you can get paint from home depot. But if you want really good paint, or you need advice from someone other than a disgruntled teenager, or you need to find products like spar varnish or powdered concrete stain go to Marks Paint.
In addition to a friendly and supremely knowledgeable staff, Marks has high quality Benjamin Moore paint. Believe me folks, you get what you pay for when it comes to paint. You think that Behr and Glidden stuff from home depot is cheap but when it takes you twice the number of gallons because the coverage sucks, you'll think twice about the extra few bucks you pay for good paint. This particularly true on exteriors.
Marks was a great find and we regularly drive past the H.D. and 2 other paint stores to get to it. It's worth it.
