Paint work is a lot of work!!! I chose to use Stewart systems to paint my interior. It is water based which I like but either way painting is quite a job! I started off with the eco-clean wash to clean all the parts. Next I used the eco-etch to etch all the parts. Etching makes little pocket in the aluminum in order for primer to have something to grip and hold on to. Finally it was time to use the eco-prime.
The humidity was low and the weather was nice that I set up a board to hang the parts out in the back yard between two ladders. I don't know if it was because of doing it in the direct sunlight, but had several times that I had to clear the nozzle because of primer build ups at the tip.
