Yes, it can. Just might be a little smelly till dried.
Yes, an interior alkyd primer can be used to prime decoys.
NO! An exterior rated primer must be used. Plus, choose a primer that is recommended for the surface you plan on painting.
Yes, the water borne latex paint manufactured today can be covered successfully with nearly any finish imaginable, including an alkyd primer. However, if possible I would exchange the alkyd with any water base primer/sealer. Costs less and the fumes aren't as offensive.
It is best to use an exterior primer outside, rather than an interior. While, the interior paint will work, it does not have the same protection such as UV protection, and fungicide protection that is found in exterior paints.
Alkyd Enamel is really old school primer. I personally would sand it with 400 wet/dry and put a coat or two of an epoxy primer over it then you can put just about any type of paint on it. If you don't want to do that, probably your best best would be n Enamel top coat , You can still get Automotive Enamels but they will be expensive because the EPA is really cracking down on the solvent based finishes. Color selection may also be limited but they are out there. And even if you use an enamel , you should clear coat it with a Urethane Clear. IT helps protect the base coat from fading and gives a great gloss when buffed. I have painted a lot of cars with Enamels and they go on fairly heavy so watch out.
Alkyd enamel is a type of paint made from modified alkyd resins, which are synthetic polymers derived from natural oils. It is known for its durability, excellent adhesion, and resistance to fading and moisture, making it ideal for both interior and exterior applications. Often used for coating surfaces such as wood, metal, and concrete, alkyd enamel provides a smooth, glossy finish that enhances aesthetic appeal. Additionally, it typically requires solvents for thinning and cleanup, as it is not water-based.
Traditionally, alkyds are found in solvent-based paints that must be reduced with paint thinner or mineral spirits. "Waterborne alkyd" is a generic term to refer to an alkyd resin that can be used in a water-thinnable paint. Because alkyds are not miscible with water, a chemical modification is sometimes used to produce a hybrid alkyd resin - often acrylic/alkyd or urethane/alkyd - that is compatible with water. These hybrids are often categorized generically under the term waterborne alkyds. A pure alkyd can be emulsified in water using appropriate surfactant combinations. This type of surfactant-stabilized alkyd emulsion has been sometimes referred to as an "alkyd latex." Different resin manufacturers use varying terminology to describe waterborne alkyds with the terms alkyd emulsion, alkyd dispersion, and alkyd latex being among the most common.

Yes it does. Many oil based primers can be used as a flat paint also. Normally, the primer will cure too hard to be used as a primer coat within two weeks, but it is a hard, flat to low sheen surface. In fact, you can make a chalkboard paint in almost any color out of oil based primer if you let the surface cure for a couple of weeks. Enamel undercoater will not work in the same way though.
You can paint the exterior of your above ground pool. You will first have to clean it and use sand paper to lightly scruff the surface. You should use an exterior primer to prime the surface, and then an exterior paint designed for the type of surface your are painting to paint it.
High gloss Exterior Oil-Based Gloss Enamel over Quality Primer will give the best results on a cornice.
I guess it would be okay, provided you use a half decent undercoat primer. Its only if you want to use indoor paint outside that things would start to become tricky. Most exterior grade paints have a high concentration of chemical in them. Some to prevent fading, some to prevent molds & mildew, some to aid drying, many of these chemicals are toxic and when exterior paint is used inside the out-gassing can be harmful.
