I would like a white primer, but any color will do. What are the recommendations for primer. I have heard mixed reviews on Poly-Fiber, and I do not want to break the bank. I just want a good UV block and something easy to later paint white over the top of it....Matt, there are two issues here: 1) Do you intend to fly the plane first in primer and then paint later? I strongly suggest that you bite the bullet and get the painting process over all at once. It will take a major cleanup/sanding of the primer if it is exposed to the 'real world' for any length of time (i.e., a LOT more total work), and there is still no way that you will have as clean a surface for your finish paint. You are asking for blister/pealing problems downstream if you wait to paint. 2) Your choice of primer. I would suggest that you choose your topcoat paint first (e.g., PPG Concept, Sterling, or whatever) and then use the primer that is specifically intended for that paint SYSTEM. Mixing and matching primers and paints from different systems can be a form of experimentation that you may deeply regret. In my mind, the amount of work involved in painting, and then repainting, is so high that the cost of the paint is a minor consideration in comparison to workability, longevity, reparability, toxicity, etc. issues.
No, I do not intend on flying it in primer, and there is a good channce I will go ahead and complete the paint process all at once. Given that, what paint would you recommend?...I think you need input from canardians with more expertise than I can bring to your question. I initially used Dupont Centari, an acrylic enamel and it lasted 20+ years. As I replaced parts (e.g., wheel pants, cowl, etc.) I repainted with PPG acrylic urethane (DAU system, which is now the Concept system) and it worked well for me - definitely a better paint than the Centari. My hangermate used Sterling, a poly-urethane and it has been outstanding. Generally, the poly-urethanes are better suited for the pros who understand the hazards of their use (toxic!) and have the skill to apply them properly. Talk to a bunch of builders and a good pro-paint supplier for advice and guidance. Experiment on something you don't like a lot before you shoot for real!
