Do NOT use this product. I had primed and painted my kitchen cabinets and doors using Zinsser oil based primer and the PPG Diamond, which by the way worked beautifully, it was perfectly smooth. A quart was only enough for one coat, so I went back to get more and the women made a mistake and gave me Timeless. I took it anyway. It destroyed the cabinet doors. That evening, I went around the grooves on the fronts with a brush, let them dry and flipped them over. I started rolling the back sides and ten minutes in, it began to clump up, leaving lumps on both surface and roller. Even if I had only used a small amount at a time, I literally would have had to change or wash the brush, roller, and tray with every 2 cabinets. The globs weren't all, even the first couple of cabinets dried with a funky rough surface, and the next morning I noticed deep unsightly marks where I had brushed. Basically not one cabinet was spared from this awful product. Keep in mind I used Wooster brand brush & roller, and I just painted an entire 900 sq ft apartment, along with one coat on the cabinets and doors using the Diamond paint, without issue. I went out and bought another quart of Diamond. Due to time constraints, I decided to just shave off the bumps and simply put another coat over the backs of the cabinets. However, the brush marks on front were so deep and unacceptable, I tried to sand them down with fine sandpaper, which only made it worse. The heat from the sander turned it into some sort of plastic like goo. Needless to say, I ultimately had to sand down every single cabinet with course paper and start over, it took hours and hours, my place is covered with dust. To be fair, I called PPG and they are sending me a check for the cost of the paint. Though at this point, the check isn't close to what it's cost me. I've gone through a ton of sand paper pads and tack cloth, had to buy more primer, rollers, trays, and brushes, not to mention 2 full days of work.
