I know most people want to use what they already have to do a project but here's a case where I think you're going to be better off upgrading your tools and chemicals.
First this thing is HUGE, that's a lot of paint to polish.
Second, unless you tell us otherwise, you're not trying to turn this into a "Show Truck", just restore the paint to higher level so you're proud of you're new truck.
So while some might recommend doing a huge elaborate buff-out process to turn this into a glistening gemstone, if it's going to be parked outside most of it's life and used as a daily driver or tow vehicle, then use the KISS approach.
KISS = Keep it Simple Simon
Invest in an electric dual action polisher, for the money you can't beat the new PC 7424XP dual action polisher. The brand and quality are time-proven and as a painter you can appreciate a quality tool.
Pick up a PC 7424 and a 5.5" pad kit of your choice, our CCS pads are real popular and a lot of people like our new Hydro-Tech pads which have a flat face design.
If you call our
Customer Support Line at 1-800-869-3011 they can help you to pick out a pad kit that will have all the pads you need to tackle this behemoth.
As for chemicals, you want to do this truck in two steps if possible but to be honest, you're probably going to need 3 steps.
We care a lot of different compounds and polishes and others can chime in with their recommendations, if you want to make this easy on yourself and still get great results then I would recommend getting the Wolfgang Total Swirl Remover 3.0, better get a quart of this stuff because of the size of your truck. I come from a Meguiar's background and love their products but one thing I like about this product is it's easy to work with, does a great job of removing swirls and scratches and it's easy to wipe off and all three of these are important especially when working on something this large.
M105 is a great compound that finishes out nice but working time and wipe off can be hard sometimes and anytime you have to struggle to remove a product or it doesn't buff as long as you want and need then it takes longer to do the job overall.
Chances are very good you can use just the WG TSR 3.0 over the truck and afterward go straight to wax or a paint sealant.
That's how I would approach this truck, keep it simple, remove the swirls and then seal it up and move on.
Here's a link to our Porter Cable page, there's a number of pre-packaged kits so look through them and if you have any questions just call the Tech Hotline
Dual Action Orbital Polishers and pads: Porter Cable 7424 : Porter Cable 7424XP: Lake Country Buffing Foam Pads
Besides fixing the paint on this truck you'll love this polisher for all your custom paint work you do, the air polisher works but it's pretty hard to beat the new PC 7424XP for a quality tool that will stand the test of time.
