Truck needs a paint job.

I have a 2003 Ram 1500 4x4 that needs a paint job pretty bad. Clear has peeled in areas and chalking up. Now heres the deal. The truck is 11 years old, has 140k miles and I actually recently just installed all new front end components: ball joints, upper control arms, wheel bearings, shocks, inner outer tie rods, cv axles, drilled slotted rotors etc. The truck drives like it is brand new. However, I feel a bad financial decision would be to drop $3k on a truck that isn't even worth more the $7k.

My idea is to try and paint the truck myself with a military grade gillespie coating, They sell a flat 34052 lusterless USMC green color. Does anyone have any experience with this type of paint? My plan is to paint one panel at a time and do the best I can prepping it. I already realize that it won't turn out absolutely perfect, but $150 for two gallons and probably another $100 in materials is a lot better than $3-4k for a professional job.

I am soon to be in the fire academy and actively looking for a fire fighter job so funds are tight and I want to keep this truck until I can afford what I really want.
