You will get opinions other than mine, but from what I have done I can tell you this. I would use POR-15 on the cab floor and cover it with POR-15 top coat flat black. I tried Eastwood rust converter on a couple spots and POR-15 on some other areas. My truck got left out in the rain for several weeks (its a long story) and the POR-15 did fine. The rust converter rusted through (surface rust) in places. Maybe I didn't put it on correctly, but I am sold on the POR-15.I would brush it on. It will flow out just like it's sprayed on. Just get a good respirator when using the POR. The fumes are dangerous to your health.

The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself." - John Stuart Mill (1806 - 1873)
