If you dont clean and spray inside your frame, all of this is useless. it will rust from the inside out...

That's great advice. But it's nearly 12 years too late for O.P.
You didn't check the date on this dead thread before responding, huh?

It would be a real test to see how the POR15 worked. Maybe he'll someday check back.

You really think OP actually went through with anything in the first place?

You could be right. A lot of people are 'talkers'. Probably crawled under the tk looked at the job and traded it for a Toyota Highlander a week later...lol

Hello everyone,
New to these forums and would love a knowledgeable response to this. My first chevys a 1998 Tahoe and well since shes been through quite a few NY winters shes rusty. the body is sound but the frame is just at this point of surface bubbling(no rot). SO is there anything tips to this?

My plan is to scrap and sand as much as i can, then rust reverse with something like POR-15 and then under coat.

I know the real best course of action is to sandblast yadda yadda. BUT i dont have that kind of time or money. So to just keep it down or just stop it is this smart? and is there any tips or tricks.

Thanks Guys, Gavin

5 gallon pail of cosmoline, thinned and sprayed over the por-15.

Fluid Film. Paintable coatings are only as good as the cleaning & pretreatment system beneath them. If I see a vehicle that's been "undercoated," I'm wondering how nasty everything is underneath that coating and how long before nasty rust blisters form & pop.

Undercoatings - Bad.

Fluid Film - Good.
