Here's the problem(s) with "Rattle cans" and "Spray Bombs": The only decent brands I ever used were Rustoleum and Krylon, Circus is all thinner. If the nossles aren't any good so much more the justification to buy a "Door Jamb" gun. Spray cans are meant for small items like garden frogs or grand-ma's iron chairs (when she's doing the work). They have a hot thinner in them to make them penetrate (good) and soften the paint that might already be there to inhance adhesion. That makes prep less crittical. My advice is to get a "Jamb gun" or a primer gun, keep your lacquer based primer in there (if it's still available where you are)and use it as needed. Now with the epoxies, you are going to have to mix just what you need, use it and clean the gun, hence the small jamb gun is great!
