Is 20 gauge OK for general body patches?

Jap crap boxes were even worse. Stamp them tokyo tonkas real thin, and pay their workers with rice to sell em dirt cheap, no galvanizing, then ship em over on a boat. Their vehicle inspection programs in japan meant vehicles got scrapped every 3 years back then and you bought a new one. This was for their gubmint to keep the machines humming and people working. They never expected that people here in the U.S. would actually keep em more than 3 years. But people did, and at the 5-7 year mark the bodys were structurally unsafe in the rustbelt states. I can remember fenders flapping like wings these rolling mechanical assholes going down the highways everything rotted all the way around, and them only bolted at the top. My brothers 79 toyota pickups bed lasted about 5 years then fell apart, and he bought the truck new. Lol

My dad had a 1974 K5 blazer. Metallic bright green, white inset panels with chrome trim. Within the first year he was buffing that white paint where tan rust streaks were staining the white paint from where the body trim holes were. He had that one about a year, figured out what was up and sold it. Bought a 1970 ford club wagon van with a 302. He kept that for years, not a stitch of rust.
