Ok; not to piss anyone off here, but what up with this paint? I just finished an Interior job with this stuff. The home owner's requested they buy the paint & it was top quality stuff with a twentyfive year warranty. Hey what ever. Now, I have never used there products before, have not gotten good feed back, and I usally stick with Porter or Pittsburgh paints. This paint was like water and did not cover worth a crap. Now the walls were sheetrock with an off white color. The new paint was like a baby sh$& brown with trim a lighter version. I think this stuff was called Duration or something close to that name. Now Porter or Pittsburgh would have covered in one coat, this took two and probally needed three what up!!! Any thoughts or suggestions would be great. Thanks
