ok bought a truck with some rust, rust already ate through some parts so there are holes. im a noob when it comes to body work. I tried reading up on it but cant find anything how to fix hole. biggest hole is about 8 inch by 6 inch. im going to fix the whole truck and paint it. its a 85 Dodge Ram 50 with 103,000 miles. 4 speed. really fun truck.

so if you have any info on how to cover those holes. I know i have to weld metal to that body, but what kind of metal and what sort of welder, gas or no gas would work.
