i found an 85 Silverado, 2WD SWB that a guy wants to sell. he's asking 1,000. straight ol truck. the thing is it's been in primer for about 10 years and it has surface rust spots on it everywhere like on the curves on the body, around the windshield seals places like that, no pitted rust or rust holes just that smooth kinda rust. if i buy it can i get rid of it without it coming back??? i hate to pass it up but i know rust worries me to death.
