We used Rustoleum spray paint to paint the bare metal frame. We are hoping it prevents further rust from forming. I painted the interior and the trunk in white primer, then in black paint. I did this to create a contrast, so it’s easier for me to see that I have painted it all. I think it looks much better. I didn’t paint it to be pretty, simply to cover to bare metal.
Next up will be sound deadening material then padding and carpeting.
