POR 15 on underbody, best option?

Over the winter I'm going to get together the necessities to re-do the under-body of the Nova. I've heard good things about POR 15, wanted to know if it's really the best thing to use to put on old metal under-bodies to prevent any future rust?

 

Also, should I get the under-body sandblasted prior to applying such a product?

 

Here's what I'm dealin with:

We used this stuff under the battery tray on my car, where some light surface rust had begun. You might already know that....

 

That said, the POR-15 company makes a variety of products actually, all a rust-stopper/preventative, but each geared towards specific uses or areas on a vehicle. I'd call them and let them tell you which of their products work best for an underbody coating. I can tell you the stuff is not at all cheap, and that on the can it says minimal surface prep is suggested, as it prefers some "bite" on the surface for adhesion. If I recall, it says for surface rust a wire brushing is all that's necessary.

 

I have a partial can at home that I'll check if I remember.

I am not sure I would replace the pan if its just surface rust.

 

If the medal is thin or there are already holes in it, thats a different story.

 

Eastwood is another option for paint supplies. http://www.eastwood.com/

 

I just recently got my subframe sandblasted and used Eastwood chassis restoration kit

It turned out really good.

 

Anyways good luck with project and keep us updated :)
