What grade pre-finished bolts? How bad will they rust?
I want to use pre-finished black bolts. I can find grade 8 and grade 5 nuts in black oxide, and some in phos oil. How badly will these rusts? Should I just get all my exterior bolts (roll cage, tire carrier, bumpers) and paint them myself? I'm painting the Jeep OD so this is a contrast. If I do that, what grade bolt should I use? Thanks for the advice in advance.
