Cascoat did an outstanding job and all the metal was evenly coated with no runs and a beautiful overall sprayed finish. Careful preparation and professional finishing should result in a 100 year airframe without rust or corrosion. The two part urethane epoxy paint system is well suited for the attachment of the Poly Fiber Fabric system. The Poly Fiber Fabric system utilizes solvents that range from the mild 2210 fabric cleaner to the very aggressive MEK (methyl ethyl keytone) all of which have no effect on the Randolph epoxy finish. You can brush MEK on the Randolph coatings all day long without ever damaging the finish. The only way to really remove the paint is a torch. During the build project I found it necessary to add a bracket or tab or make a repair on the painted tubes and the easiest way to do this was to burn off the paint in the weld zone, clean it with MEK and repaint it with the same Randolph coatings. It was almost impossible to see where these repairs were made.
