I have a Dune Beige 80 fj40. The paint on the dash, wheel well humps and and walls is still in good shape but the floors are starting to show a bit wear and Im thinking of putting Durabak down. All Im gonna do is the floors and up the fire wall above the fuse box. What I cant decide is if I should go with the light grey to try and get a close match to the beige interior or go dark grey to match the seats and contrast the humps and walls. Also if anyone knows the best primer to put down after sanding and before the Durabak(zero rust,build primer,red oxide) that would be a big help.
