Auto Mats How Do I Wax My "New To Me" Truck?

How do I wax my "New to me" truck? - auto mats

As always something waxed, as I wash, then wax my "new to me" truck?

I washed the car last week in the car wash mat, and I see scratches and bruises that I have never seen before. I wash out the previous holder of repairs? Moreover it can not afford a coat at this time (new tires first), and it seems that the layer above the paint peeling on the cab of the truck. How do I get the truck look to kick *** without spending much money?
