97 xlt under body rust protection?

[IMINYOURCHAIR]

Hi, I am on the path of moving up to Michigan from north Alabama (family up there). Here we don't have rust problems like they do in the winter and I know these trucks are prone to rust. I was curious as to what to use to protect it and how to apply it. and what else I could do to prep. I will drive the expy all year unless I can get a second vehicle but it would still likely end up being driven in the winter being an suv.

If you can prep the surface correctly (like putting it up on a rack, de-greasing and powerwashing it) undercoating or spray in bedliner will work great. You really need to get any loose scaly rust and grease off of every part, or you're just wasting your time.

Expect to spend 3 or 4 times as much time prepping the truck as you will spend spraying it.

It's also time to get the Dr. Color Chip out and take care of any paint chips and then give it a good wax / sealant.

sounds like plan. too bad I don't really know how to go about lifting the body from the frame so that I can really get everything sealed up.
