Seems to me that my paint guy advised against high build type primers, saying that they were like cellulite on a pretty girls legs. Looks nice until you look close, but then minor imperfections because of the high levels of chalk in the mix? Is chalk the right term? I'd have to go back to him to be sure, but thinking he wasn't a fan, saying they were a shortcut that carried a downside.

I'm a fan of the U-Pol fillers. Top notch stuff, along with the glaze product.
