You can use Testors paint, but you will still need to fuel-proof the cowl. The propwash will still blow a mist of oil there, not very much at all, but enough to eventually make the paint peel. Try LusreCote clear over the cowl paint. If you let the undercoat cure for a week or so, and LIGHTLY mist the first couple of coats of LustreCote on it should work. A heavy coat over uncured paint can craze the finish, as LustreCote is a lacquer. You can also clearcoat the Solartex, it will fill the weave a bit and make it easier to keep clean. The weight is negligible and the Cub can gain a good bit of weight without problems (mine weighs over ten pounds) Ca will bond the dummy to the cowl, use thick or gel and make a tiny fillet around the edge.

I would also add a layer or two of 1/2 oz. fiberglass cloth inside the cowl, and the "chin" area, where the carburetor air filter is on the full-size, needs even more, as it is the first part to make contact when you nose the plane over (and you WILL, at some point)

This kit was my second plane, and first scale build. How do you like it? It goes together really nicely. What engine are you putting in it, and how will you mount it? Are you building the wire gear, or using a scale aftermarket gear. A true bungee action gear really helps the way it ground handles. If you do use the wire gear, take pains to put just a tad of toe-in into it, and try to keep it even. This will also help the ground handling. Hope your build goes well, post some pics. Ken
