Like the Chevy trucks I'm seeing missing paint on the hood. No rust, so it must be aluminum. Are most vehicles all aluminum nowadays or just certain panels?

New vehicles, or older ones? Peeling paint was a big problem in the late-80s and into the 90s, as new EPA-friendly paint formulas came into use. All manufacturers. Dark blue, silver and white were especially bad.Like the Chevy trucks I'm seeing missing paint on the hood. No rust, so it must be aluminum.

Or galvalume maybe? It does look like galvanized steel though. Never really took a good up close look at.one.more like galvanised, which can also reduce paint sticking properly. Aluminum use is rare and if they use it they advertise it.
Yeah, usually its the white vehiclesCheap painting process. You hardly see paint issues on German makes regardless of brand.
White paint is notoriously difficult because of the required base coat thickness. Some automakers have figured it out but it's more expensive.
They are submerged in a bath and the primer is electrically bonded to the body. I can find out the name of what GM uses if you guys want.Or galvalume maybe? It does look like galvanized steel though. Never really took a good up close look at.one.

That just looks like it was never waxed. Im talking about paint that still looks good, then randomly gone off the hood in 2 sq ft sectionsBeen a problem for years. The paint on my jeep comes off in sheets when it's not coming off the hood in small pieces

The hood is SMC - Sheet Molding Compound. It is a mixture of resin and long glass fibers. Charges are placed in the mold, and the heated mold is clamped. The edges are trimmed after molding.Like the Chevy trucks I'm seeing missing paint on the hood. No rust, so it must be aluminum. Are most vehicles all aluminum nowadays or just certain panels?
