Underbody coating

[brotherGood]

Well, planning on doing body/paint this winter, so I'll be looking into getting the underside all cleaned up and painted/protected. I'm guessing take a wire brush to the surface imperfections (everything's pretty solid underneath, just has some scaly surface rust spots.) and spray on something to coat and paint it. Question is, what? Also, is that the right idea..or anyone have other ideas? I may have access to a lift..so that'll make everything easier.

I'm probably doing the same thing with the fleet as far as the underside. I was planning on rolling on the POR-15.

I'm planning on using Monstaliner, it's like Line x, or Rhinoliner but it has a smoother texture. Color choices too.

How much of the POR would I need?

Is this what I'd be after?

I was going to buy a gallon of this and see how many cars it'll do. I'm rolling it on. For an entire underbody I can't see a spray bomb covering that much.

Ya think maybe a qt would be enough for 1 car?

Depends how much you're doing.
I'm doing everything I can reach so I'm thinking two or maybe three quarts for me so i might as well just grab a gallon.

Really just enough to cover everything. Its paintable I think..so if anything, I'll spray black paint over top
