It is time for me to put some kind of coating on my RV7A panel. I plan to make it either a dull Black, or maybe go with my Medium Grey interior color. I have ruled out powder coating after researching some on it. They want to coat the back side of the panel or charge alot more money to mask it off with high temp tape. So I am thinking of just preping the aluminum as normal with etch and alodine etc. and go with a good epoxy paint, but I am interested in learning about other options. I have heard of one person using what sounds like undercoat spray for under our cars with good results. Hammerrite spray cans I have heard of also. I am concerned about chips around countersunk screws that I will probably have in and out several times. Any suggestions or recommendations are welcome.
