yes the rs-mmmaxxmudd-LL out does ME by a fair amount but there will always be a big demand for the 'one stop, 'one quart', 10 buck, easily applied solution that UPW, silverscreen, misty eve offer.
With the rs-mm mix 1 quart UPW gloss, 1 quart UPW flat, 1 quart deep base, 5 bottles of creamcoat, however many cans of minwax...and now you're feeling quilty not spraying such an investment, and then you feel wasteful that there are two screens worth of paint still in the can after you're done.
The reign isn't over in. The quick, cheap and easies will always have their place. Just not with me, so I'll be giving your mix a go.
