I need to patch a couple of sections of my longs (inside the car) as well as the rear firewall. What gauge of metal was used for both of these?
I HATE rust. (IMG:style_emoticons/default/headbang.gif) |

Fenders, door skins, replacement panels and most of the rest of the car is definitely NOT 18 ga. The car would be very heavy if it were. 20 ga maybe, but not 18 ga.
Paper is way way thinner than 22ga steel. The difference between 20 and 22 ga is only .006" Here are some thicknesses and weights: 24 ga. = .024" = 1.000 lb/sq. ft 22 ga. = .030" = 1.250 lb/sq. ft 20 ga. = .036" = 1.500 lb/sq. ft 18 ga. = .048" = 2.000 lb/sq. ft 16 ga. = .060" = 2.500 lb/sq. ft 14 ga. = .075" = 3.125 lb/sq. ft 12 ga. = .105" = 4.375 lb/sq. ft 11 ga. = .120" = 5.000 lb/sq. ft 10 ga. = .134" = 5.625 lb/sq. ft Most anything over 10 ga. is extreme overkill on a car. For reinforcement, you can use heavier steel if you like.... |
