We annually tend to a fair number of stake blinds that are 12 feet wide, four feet deep, and about six foot high across the back -- a fair amount of square footage. I am looking for a cost-effective way to coat both new construction blinds and some of our older ones with a flat, dark stain or paint that is inexpensive enough to justify purchase but will still provide some good protection. We have been living off the "oops" shelves at the local HD and Lowe's, but painting 36 sheets of plywood for new builds this year, it seems like there ought to be a better way. The good stuff (heavy stain with the long life) is going for $166 for five gallons, and that is a little rich for the program. Anybody got any ideas for mixing/stretching/blending/buying cheap that would help? Thanks, Rufus
