This is the way I would go:
This stuff looks awesome but it looks really really permanent from my resesarch for my frame: http://www.kbs-coatings.com/blacktop.html there are prepping steps first.

And for the inside of the frame this looks great: http://www.eastwood.com/internal-fra...ay-nozzle.html

From what I have read, most everyone sings the praises of Por-15.

The reason I prefer the KBS stuff from my research nothing and I mean nothing removes it once it dries it impervious to all compounds/liquids inluding walter salt even tougher stuff like acids. Sounds like nothing will remove it period once it hardends, its even impervious to UV.

This KBS stuff ...its a kit..with multiple processes... more things to do = more to mess up... and ..how many gallons of chassis paint does it take to get a good amount of protection on the frame? I live in NJ so I assume more is better..and once I get one coat of..lets say POR 15..once its dry..can I put another right over it? or..

Anytime bare metal is being coated you cannot just put por-15 on it it needs a primer of sort otherwise it will crack off. KBS has 3 steps the first is to clean the metal if you skip that even with por-15 and primer you will get less than desireable results.

Inside is the most important. That is where wet mud and sand will sit for years and rot it from the inside. You can always clean and repaint the outside. We just finished putting six feet of 5" x 3/16" plate on the CJ's frame to fix the rust holes and cracks. If I could remove all of the rust slabs from inside the frame they would probably weigh 10 or 15 pounds. We found the bad spots a spot at a time. Had we starting beating on it with a welding pick/hammer and found all the bad spots all at once, I would probably have gone with a new frame.

One guy taped off all of the holes, poured Por-15 or Chassis Saver inside and rotated and tilted the frame until every inch inside was covered, then drained the excess. That is what I would do. Maybe twice or three times. Now if you live in Phoenix, that is probably overkill. On the other hand, that inside spray idea using one of those killer coatings might be easier.

I just painted the frame (outside only) and a half quart of Chassis Saver gave me one coat, brushing it on. $40/qt at NAPA.

All metal has rust even new metal along with moisture that is captured in the coating process that causes rust under the coating (and through it eventually as the coating degrades) unless the coating you use is made to stop rust and encapsulate it and the coating doesn't degrade. You can reduce the moisture captured under the coating by heating the metal you are coating at coating time.

The guy in ths thread said por-15 came off even with the prep/primer step: http://www.jeepforum.com/forum/f8/pa.../#post12229136

I just hate to see you get a new frame and not protect it properly.

It doesn't matter what you choose, there is never going to be a one step solution so get the idea of "simple" out of your head. With a new frame you are going to need to find a way to clean and degrease the inside before it's coated (whether it's getting primered, por'd or otherwise) or nothing is going to stick to it. Oils, dust and debris from the steel mill and construction of the frame are going to be in those frame rails and trying to get anything to stick to it properly without good prep is fighting a losing battle.

Besides, you spent a bunch of money on a new frame why wouldn't you want to be tedious about protecting it to ensure it never needs to be addressed again during your lifetime? With all the threads about new parts and options for your build I see on here it looks like you have alot of work ahead of you. Here's a friendly tip, don't rush or half a$$ anything just to get it done and see the finished product or you'll be going back and re-doing things again.......costing you even more $$$.

Powder coating? I don't think that is a good choice.

I've spent years agonizing over this question and I believe I have the answer! First buy a cheap undercoat kit. I've got 2 one was a professional and the other I believe was JC Whitney. I sprayed POR=15 inside the frame using the long wands and various nozzles (360 degree) that came in the kit. Now spray the exterior of the frame with POR-15, allow to tack up (1 hour) then coat with whatever color coat you want. My case it was a cheap Plum crazy purple. The fact that you sprayed the color while it was tacky, means it is stuck to the POR-15 hard. POR-15 is the original rust paint, everyone else is a pretender. Sandblasting will not remove this paint. My frame sat outside on jack stands for a couple years and the only hint of rust was a tiny pin hole size spot on a weld. Man this thing was beautiful after 2 years. The Jeep is not done, so no real world experience, but I believe you can't go wrong. POR-15 only negative is it is not UV stabilized. Not a problem following my procedures. You won't be disappointed.
