Looking for a specific primer

[DeltaVee]

Somewhere I read about a commercial spray can primer that came in "light fill, medium fill, and heavy fill." I thought it was Duplicolor but it was all the same stuff at an auto store near me. Is anyone familiar with such a product? The stuff I bought is Duplicolor scratch fillre primer. I'm going to try it out on a not-too-detailed dog of a don't-care-if-it-works kit. But I'd still like to find a nice alternative to the pricey Gunze stuff I've been using. Thanks.
