I posted this on another board pertaining to interior walls, but maybe this one is more appropriate...
Though I normally do not shop at Walmart, I have come to like their interior satin "colorplace" paint, in a shade which I use in all of my rental units. The last batch; though appearing to be the same stuff in the same can, seems to be thinner and tends to run and drip much more than I am accustomed to. Has anyone else had a similar experience, or perhaps have knowlege of a switching of paint suppliers to Walmart recently?
The five gallons I bought last month were just fine. The stuff I bought today is CRAP.
