On these doors and cabinets I used 2 different primers. The 1st one being Zinsser Cover stain classic oil base which preformed well when completely dry. It is now formulated to be compliant with California restrictions I guess. I could go over all the surfaces with 220 sandpaper , no problem. it says it is low VOC content but I still definitely had to where a respirator blow out the pilot light to the heater and keep the room well ventilated. I did have to strain it with a pair of my girlfriends panty hose because they don't sale fine strainers at paint or hardware stores here any more, since everything went latex.
The second coat I used Dunne Edwards ULTRA-GRIP Premium
These where the selling points.
Excellent adhesion to properly prepared drywall, wood, and masonry, as well as hard-to-stick surfaces, such as aged alkyd, aluminum, galvanized metal, vinyl, fiberglass, and select plastics Outstanding stain-blocking Strong tannin resistance Great hide and excellent enamel holdout Ultra-low VOC contentThe finish was 2 coats of Kelly Moore's Dura Poxy. which dries very hard and is very durable.

In trying to find the right combination of products I think we did pretty well, and the customers where very pleased
