: por-15 experiences

07-09-11, 12:49 AM
Hi all. I have a 94 fwb in pretty good condition, very little rust on the underbody. I'm thinking of using por-15 to seal the frame and floor pans to prevent anymore moisture from attacking the metal. Has anyone had good results with the product?

This dude I know swears by the stuff. He came over just covered with the stuff, took like 3 weeks for him to get it off his skin. I'm not sure what he has used it on but I think he put it on his truck somewhere.

As long as you're using it on surface rust, and not on rot, it works wonders. Just remove any excess rust and/or flaking paint with a wire brush first. AND DON'T GET IT ON ANYTHING YOU DON'T WANT IT ON. :)

I can confirm that the stuff works just great, and it doesn't come off your skin. If you don't take it off with rubbing alcohol immediately, it's there for a long long time. I did my wheel wells and lower rocker areas with it. Very easy to work with, and it really does dry rock hard like they say.

One word of advise, if you intend to use it more than once, don't get any in the groove in the top of the can where the lid seats. It dries like cement and you'll almost need a jackhammer to get the lid off.

I never had good results with the stuff. I'm sure the company would say that I'm too stupid to use it right. My preferred method is to brush naval jelly on any rust, rinse it off and cover with Carquest Chassis black. The Chassis black is what the Gov't specifies for their Hummer refurbs. I don't know if other parts stores sell something similar. It is a hard slick coating and dirt and mud seems to wash of pretty easily. It sticks to bare metal too and primer isn't required. If I'm really anal about a super nice car i will use epoxy primer under the Chassis black.

does chassis black come in a spray can or do you have to brush it on?

Isn't that just semi gloss black spray paint?

I've wanted to use naval jelly but haven't done so yet. I had to remove the vinyl top from the '76 hearse as it was severely damaged, and the metal underneath has surface rust but no rot. Not sure what to do with it yet.

I used naval jelly to get the rust off of a set of Cadillac wire wheels. The stuff is magic.

How good it works really depends on where you are and what your rust really looks like. Depending on what your rust really looks like you could be doing more damage painting over it.
