I coated the top of my new floor today with POR-15, and I'm wondering how would be the best way to coat the underbody. I could do POR-15 on it as well, but it seems like it would be a huge messy hassle laying on the floor dripping that stuff all over myself. Is there another good way you guys would recommend to coat it? I've used rubberized undercoating before, but I don't think that stuff is very good at preventing rust on its own. I also bought a quart of epoxy primer to do my quarter panels, but my spraying setup isn't ideal (tiny compressor, no booth, no filter/dryer) so I'm having doubts about spraying any more than I really have to. What would you do?
