Rust Removal, Treatment and Prevention

[bcjones1017]

I have looked at other threads but didn’t find what I was specifically after.

I have a 1999 Sahara and want/need to treat some rust spots along the frame and other places and replace a floor pan. Here are the things I seek guidance on.

1. To treat the inside of the frame I am planning to remove as many flakes, etc from the inside and considering using Eastman internal frame coating. What is the best way to remove any flaking and is Eastman a stand alone recommended product.

2. I need to replace the passenger floor pan. I plan to cut out as much of the floor as needed treat the margins with Eastman rust converter, inside and out, pop rivet a new pan in place then paint with Eastman rust encapsulator. Is this the right method and are these the right products to do the job? Do I still need to paint or can I skip the encapsulator and just paint after the converter?

3. Other areas with light surface rust I want to sand, wire brush the surface rust and spray with rust converter or encapsulator. Have I got this right or do I just need to use converter and a paint?

Long post. All feedback appreciated. There are so many products out there and I don’t think they explain the sequence of product application very well for different scenarios.

Question #1 - for cleaning. Then the rest of your plan with the Eastwood. Coat hanger to keep the tube stiff when you push it in the holes. Be sure to drill drain holes as well.

Thanks for the video. I assume if I bust all of the flakes up on the inside drill drain holes and maybe used compressed air, I can get most of it out of there. Don’t really want to use water but if that’s better I am in. Would you use water or air?

I used both water and air. Let it dry for a couple of days before trying to spray the inside. I picked up that auger at Lowe's.

For surface rust on the outside of the frame, I recommend POR-15. I used it on my frame last year and it’s held up good so far.

I’ve also heard good things about fluid film, it’s something I’m going to try this year for extra protection. It seems pretty easy to use so that might be something to look into as well.

Made up a chain flail out of a 4' section of plumbers snake and some small steel chain twisted in. Really slams the frame internals at 500 rpm's.

Try this instead.

I used to use Fluid film but switched to Wool Wax, I found FF is more susceptible to thinning out and dripping all over the garage floor when it gets really hot. I have never had that experience since I switched over to WW. I use it on both my jeep and Toyota Tundra frame and have not seen the rust get any worse now in four years, FWIW.

Just doing some reading to see what others have done. I coated the inside of my frame of the LJ with 2 coats of 3M cavity wax, and the exterior with 3 coats of Amsoil HD Metal Protect. It has served me well on the Gladiator for a few years.

The TJ is a different story. It has some surface rust. I have looked inside the frame and it's mostly untouched, and several years ago I did internal frame coating with Eastwood (the green stuff). But, now that it will unfortunately see winter mag-chloride and rock salt (over the pass) I need to sort things out before it happens. I am currently considering wire brushing as much rust off of the frame/body as possible, prepping and painting. But as for long term. The current though is the same treatment as the LJ - 3M cavity wax, plus HD metal protect. Only after that treatment dries, I am also considering applying a box full of fluid film I have sitting in the basement. I never used it on the Gladiator once I realized how nasty that stuff is, and the Gladiator did just fine with only the cavity wax and metal protectant. Although these newer vehicles have better paint and coatings on them for rust prevention than our older TJ's.

So, curious if anyone has ever mixed fluid film over top of a 'waxy' protectant before. I am hesitant to do it - that stuff I have heard is just so nasty. But I really don't want to destroy the frame in a couple years.

If it makes a difference, I will probably only really drive at most once a week in the stuff, however, the closest car wash to get the underside rinsed off is in town 60 miles away. So even a grocery store run will leave me with the inability to rinse off.
