I started out using Traditions acrylic. About half way through painting a dozen canvas geese, I came to the realization that for the price of a 3 oz tube, I could almost get a quart of latex. Aside from a brief (and frustrating) foray into oils, I've been using latex for all my base coating and major feathering and shading colors for most of my decoys. I keep a full selection of artist acrylics on hand, for mixing small quantities for bills and such, or mix up a new stock color to take to Lowes and have a quart blended. I like their Olympic flat exterior, one time they were out and subbed their better brand for the same price, but I found it thicker, and when I stimpled in left air bubbles on the surface. I like having the "stock colors" on the shelf, so if I goof (or when) and need to go back and rework an area, I'm not stuck starting from scratch mixing colors. Likewise if the rig needs a little maintenance between seasons, easy enough to grab the can(s) off the shelf and touch it up. Generally I keep in stock white, black, raw umber, burnt umber, "hen tan", and several grey or brown recipes that I have mixed up for different rigs. I have been priming all my canvas deeks with 2 coats of thinned latex kilz (including the wood head) and been happy with that base. The label on kilz gives a maximum recommended tinting, I've been thinking of on the next gallon of primer having them add whatever that amount is in RU so if the top coat wears and the primer shows, it doesn't' show white.
