I have recently started a restore on a 72 Cutlass and have found some major surface rust through out the interior, mainly behind the headliner padding. I am relatively new to this kind of project and was wondering what is the easiest/best way to get rid of this rust? Alot of it is behind braces and in hard to get to places. I am considering an acid dip or sandblasting, but was wondering if there are other alternatives.
