Yes, an interior alkyd primer can be used to prime decoys.
I wouldn't. I don't think they would have called it "interior paint " just for fun.
Primer made with alkyd base.
Yes, if the primer is oil-based too (alkyd is good too)
First, clean the tile and grout with a harsh cleanser such as T.S.P. Next, apply a bonding primer to the tile with a brush or roller. It can be oil-based or water-based, and you can thin it slightly if needed to get a smooth, even coating. Once the primer is dry, apply your alkyd (oil-based) paint over the primer with brush or roller.
Yes, it can. Just might be a little smelly till dried.
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.
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.
I think you would want to prime it first with an alkyd primer. Then what do you consider "roof paint"? It should be something suited for exterior painting if its outside! Just make sure it is designed to stick tou your primer. There is more detailed info at http://www.jjwpainting.com
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.

In the past oil paints referred to either petroleum based paints or linseed based paints. Today in the USA petroleum based paints are no longer sold and it is difficult to find linseed based paints though they do exist with a small proportion of linseed oil. Alkyd paints are made with synthetic oil and are readily available and have come to be known as "oil" paint.
you must first sand it so to remove any shiney surface then put a primer like bullseye then an all surface paint usually an alkyd or oil based
