This one may get filed in the "barely perceptible" category, but yesterday I stripped and primed an earlier smugglers box lid. The factory modded the lid a bit when they ran the brake lines down from the new power brake MC, which I no long have.
RUST!!!! This confirms for me I made the right decision going with a galvanized chassis. This single part from an early car had more rust on it than my entire '78 tub!!
Stripped and blasted - nearly there.
The difference is slight. I wonder if I should fill those little holes in the lid. Not sure what they are for, but I'm not using them........
