I know I'm not a -14 guy, but why paint the interior? Mine is Akzo and will remain Akzo on the inside on purpose (tho truth in advertising, I have a military exterior scheme planned).
More interior paint is just weight, and if you do side panels, carpet etc, what's gonna be seen.....or opposite thought, just beautify those areas that you wont be covering in someway....
