If you are only looking to get your truck back to a daily driver the way it looked when it was 2-3 years old and not blue ribbon show quality you could do what I am. I am a jack of all trades and pretty good at some. I have next to no experience with a paint gun. I have been redoing my 54 3100 one piece at a time. I started with the bed. It did not have one when I bought it. I located one in a salvage yard. I had the original fenders. To keep this short (too late) I stripped and repaired the parts. next, don't anyone laugh, I have been painting the parts with a can of rustoleum Acrylic Enamel automotive spray paint. Yes, rattle cans. Granted, the finish won't be as hard as a paint job from a spray gun with hardener in the paint but it makes for easy touch up. I don't have to drag out a bunch of equipment and set up in a paint booth. I painted these parts and pieces in my driveway. Click on the link in my signature (My 54 3100) to see a slide show of the progress as I worked on this or click the link to see the end results. Bed, bumpers, grill and running boards are all rustoleum spray paint. I have not painted the dog house yet.
