Big fan of POR 15 too. Being using for awhile now. I started with the little starter kits because I was just doing these little areas. My initial research seemed to indicate that POR 15 did not store well. So the little that was left after I did what I wanted to do in the 4 oz can just got slapped around under the Jeep with no prep. Figured what is the worst that could happen. Have since discovered cause now I buy bigger cans that you place some saran wrap over the top, seal it, and put it in the fridge it holds up just fine. Well on rusty metal with no prep, no wiring brushing, no cleaning, or no metal prep, it worked. See the shots below of my gas tank heat shield. I did that 2 years before I took it off cause I hung a gas tank skid. Did it with it on the Jeep and you can see where I could not get at. Now with the unprepped cleaner metal it just peeled off. When ever I open something up I do some housekeeping and POR 15'ing. Like when I hung a whole new exhaust from the front cat, '00 Jeep, back. On cleaner metal I have gotten in the habit of wire wheeling the metal, using more metal prep, and for a longer period of time. I am at the point where I am buying metal prep by the gallon. Jury is still out on how well it will hold up on the cleaner metal.

 

Ralph77, you are the POR15 posterboy of these forums. When I think POR15, I think Ralph77.

WWRD? (What would Ralph do?)

He would POR15 it. lol

 

On rusty metal I could not be happier. It is the cleaner metal that I still wonder if I am doing the right thing. As opposed to some sort of Chassis Saver products. Or maybe Monstaliner? As you know I have done all the brackets and everything associated with my tow hooks. The whole front before I installed the tow hooks. All three skid plates. Plus all the hardware for the factory running board install. All cleaner metal. Time will tell if I made the right call.

 

I used the Duplicate-Color Professional Undercoating on my wheel wells. Love the stuff. I also used it to coat the bottom of my after market fender flares in the area where water and mud would get thrown up at them.

 

Or something like that. In a perfect world I would completely dismantle the Jeep. Gut it completely. Wiring and all. Take off all the doors (remove glass, locks, door handles, etc), fenders, and hatch. Send the whole thing down to Line-X and have them go to town.

 

A boy can dream lol

 

In a perfect world.. yes... you're definitely not alone. Maybe some day I'll have more money then sense. lol... but until then... it's just a dream.

 

Curry... I've used something like that on those types of areas on vehicles before and have had good luck with it. Guess I'll have to come up with a good combo of what to use where to hit the whole thing.

 

Yep, it will probably take an undercoating “cocktail” if you will. I like the dupli-color stuff because it is rubberized and really seals up gaps. It eventually hardens or I guess the better phrase would be sets-up. It doesn’t get super ridged but has a little give to it. You can see the fender flare coating I did in my build thread.

 

does it have a similar cured property as say rubberized bed liner?

 

It very well may be like that, I have never interacted with rubberized bed liner. Like I said it gets hard, but still has a little give.

 

Sounds a lot like it to me then. my last good 4x4 before I moved overseas was a Toyota Tacoma ext. cab and covered the bed with that stuff. I like it better than the Rino lining because the tough yet rubberized texture of the cured product kept things from getting scratched up when moving them from A to B. The Rino stuff is tough, but hard... and cured product is likened to 80 grit sand paper. IMHO.

 

Bedliners dry hard,If its rubberized its undercoating.Its best to use rubberized under coating because if rocks or anything hits it will bounce off with little to no sound.Bed liner will ping a little when something hits it,And depending the brand bed liner it could even be knocked off if hit hard enough.

 

yeah... I covered the inside of the bed of my Toyota with it...not the under carriage.. you're right, that would make a good amount of noise.

 

I'm gonna keep my eye out for better deals on the fluid film. Just saw it available at a local parts store near me today... at like 12 bucks a can. Does that sound reasonable to anyone who's used the stuff before? I'm looking at protecting the full underside of the Jeep...so that could get expensive quick. It doesn't look like a can of that size would adequately cover that much area. And there's a lot of real estate under an XJ. lol.
