Scrubbed the interior surfaces that I want to paint, with a very coarse scotch-brite and soapy water. Rinsed with clear water and towel dried. Also prepped some panels and other items that will be installed later. The plan is 2 part epoxy primer, base coat and 3 clear coats. I ordered my interior today from Flightline Interiors. June 22nd delivery date. Picking up my Dynon D100 EFIS tomorrow. Should be the last purchase other than that "cheap" 406 ELT. Hoping the prices fall a little as the competition increases.
