POR-15 of my CJ7 Interior Body Tub

Hello all! I purchased an 86' Jeep CJ-7 Laredo last summer while I was working in Afghanistan. I had my wife pick it up for me from NC sight unseen, but with high expectations....(fingers crossed).

Luckily when I was able to see it for myself, I was pleasantly surprised to see that it had the drivetrain that I was hoping it had (258 I6, T176, D300, D44 rear end).

The body and frame are very solid, but I have decided to do some preventative maintenance on it to keep the ole rust bug from destroying it in the future.

Here's the plan:

1.) Strip the paint from the inside of the tub (apparently POR-15 claims that it needs to either be painted onto seasoned rusty metal or on bare metal....but not over paint).

2.) POR-15 the "new" bare metal interior

3.) Line-X the interior (still deciding on whether or not to do this step)

I realize that some will say to do the same to the underside of the tub, and I might do that eventually depending on how smoothly this first stage goes.

I started out using some Aircraft Paint Remover to remove the paint. I've never used this stuff before, but let me tell you, it REALLY works well.

Basically, you spread on a layer of this stuff over the surface that you want to remove paint from. Be very careful to not get this anywhere that you don't want the paint to come off.

It is apparently very caustic, so wear the proper protective equipment (gloves, goggles, long sleeves, etc.). Also make sure to do this in a well ventilated area, as the fumes are relatively strong.

The product causes the paint to blister up after about 5 min. After you feel like it's blistered up enough, use a plastic scraper of some kind to scrape off the old paint/primer that is now mush. Please dispose of the remnants properly....a clean planet is a happy planet. Rinse the work area down with water to neutralize the paint stripper, then dry it off and admire your handiwork.

If you are not going to use POR-15 to your bare metal floor pans, you will want to primer the area to prevent flash rusting. Since POR-15 is made to go over rusted surfaces, I'm not too concerned with the flash rust issue, so I'm leaving them as is until I get the whole thing done and ready to be coated with the POR-15.

This is what the passenger floor panel looked like after using the Aircraft Paint Remover (post clean up)

I POR-15 the entire inside of my tub. Scuffed everything and went right over the paint and the light rust. There's a few places that I didn't scuff or clean well and the POR-15 flaked off a bit. But 99% of it is still on there solid (I did this about 6-7 years ago).

Here's a pic of it part way completed.

No I haven't - It's been a while since I researched similar coatings. I did this back around 2006 or so. All in all, i'm very happy with the results from the POR-15. That stuff is a freak of science, while working with it I slopped a bunch all over the tub and got it on around the base of the can. I left the empty can sitting on the tub over night and the POR-15 damn near fused the can to the tub. I could literally grab that can that was attached to the tub and rock the whole damn Jeep.
