1986 RX7 base model resto-mod project

[need RX7]

I do like the idea of a spray-on deal, rather than something that requires sliding around under the car brushing something on and dripping it all over the place and what not. I probably don't need something like POR-15 and the like, since I plan on never driving in snow (and waiting a few rains after winter to wash the salt away), and washing off the undercarriage regularly.
