Hi folks. I have a '49 1/2-ton chevy, and I'm ready to start working on the cab. There are probably as many answers to this question as there are trucks, but I'd like to know how most folks paint their cabs?? I'm particularly interested in the floor, interior/exterior firewall, and underside. Do most of you use POR-15? I'd like to stay original with the dash and doors, which I think is brown. Thanks.
