Frame painting advice ... Bare metal???

This car is going to be a driver, so perfection is not necessary. However I am balancing that with my son's desire (and initiative) to get his frame painted.

Product advice? Lets say we want "very little visible rust in 10 years". Is POR 15 the way to go? I would be nervous trying to so that in my driveway.

Take a look at the pictures and let me know!

Thanks,

Eastwood (and some other places) have what is known as a "rust converter". It is the chemical used in POR 15 that chemically changes Iron Oxide (rust) into Iron Phosphate, a tough waterproof barrier. POR 15 will not flow into the riveted joints in your frame. This stuff is like water. It will wick into the joints of the frame and stop all of the rust in the joints where POR 15 offers no protection. At 15 bucks a gallon, it's cheap insurance to treat the joints and fasteners with this then apply por 15. Incidentally, sunlight breaks down POR 15 in just a few weeks so, a top coat of any satin black solvent based paint is a good idea.
