Rust prevention

khaki2020offroad · Oct 27, 2020

Hey all

I saw Another thread about a frame that rusted way beyond what it should have in a short amount of time. My question is: what is the worst body rust anyone has seen on a third gen?

my 2018 Colorado did not get any rust before I traded it in, but the next owner also should be good for the life expectancy of that truck. I took it to my buddies body and paint shop and had a cavity wax sprayed which prevents rust inside the panels that you cannot access. (It was made for after welding removes the galvanized protection)
I also did this with my 30 year old blazer after I bought it and cleaned it with a marine grade salt water remover.

Does anyone know of anyone that has tried the cavity wax?

Gonna get my truck sprayed next week. Should be $150 for some serious piece of mind.
