Howdy, I got some POR-15 for my car, and it looks like I'll have some left over so I wanted to coat some of the more common trouble spots on the underside of my '07 SCrew. It's a Texas truck, so there's no rust yet, this is preventive. But I'm in Michigan for the winter, so salt and such could mess it up.

So where should I coat first? What are the common rust spots?

 

I'm not sure what spots normally get rust since I live in GA, but I've heard about lots of peoples exhaust rotting and falling off on the highway. I would coat that and the frame and maybe the wheel wells.
