I’m looking at painting an all aluminum airplane project myself. Why? Just because I can! I don’t mind working with the hazardous materials and will take appropriate actions to limit personal exposure, but what I can’t find is how to control material runoff. The plane is a 6061-T6 aluminum and I plan to acid etch, rinse, alodine, rinse, and then paint. Since I’ve never done this, I wonder how much runoff there is and should I be concerned? This will be done on property that is still using a well for home water. Any one have photos on how you handled this problem? Any and all advice will be appreciated. Thanks, Michael p.s. I’ve noticed PreKote chemical in Aircraft Spruce’s catalog, but since it’s new I’m not sure how good it is. Its milspec, but I’m not sure that really means much!
