As spring approaches I start planning work on my tractor (sorry, YJ
) and one thing I've been thinking of is to anti-rust those hidden places like inside of the frame, windshield frame, etc. Due to specifics of the location
it's a chemical work only. In ant case what's the better way to approach it? Also, does it make any sense to use foam to fill some of those or it will be more harm than benefit? Thanks for any thoughts.
