Hi:
I have gotten sort of annoyed with POR-15 for several reasons. One of which is that I have had a hard time getting the stuff to keep well . . in other words, the pint can lid gets nicked up after it's been opened/closed a few times such that the rest of it skins up and basically dries up. Second can I bought, I carefully used a piece of saran wrap in between the can and the lid (per their instructions), but it still skinned up and went bad. Additionally, after I painted my cage with it, I realized that UV rays will destroy it, so i spent $$ to buy a pint of their "top kote" brand paint that is supposed to be UV proof. Long story short, it's not working as advertised.
There are a lot of other products out there. Eastwood Rust Encapsulator, etc. I was hoping some of you smart folks would have some good advice.
Use will be generally everywhere, interior and exterior. My Suburban has some body panel seam rust (prepping for Line-X on the interior of tub, possibly interior roof, possibly wheelwells etc). All advice is appreciated. Thanks!

It turns rust into a primer, here is pics of the tire mount I just did. 


Just wire brush the loose rust off, blow it off, then brush the Corroseal on.
