I found one in a small paint chain. The package says "for water based
paints, acrylics, and latex flat - thin at 3:1 ratio." Two problems
right there. I'm not going to use flat, and the paint I plan to use says
not to dilute more than 1/2 pint per gallon, which works out to 16:1
paint/water ratio. Far too thick for the Preval.
