Lets have a conversation about rust prevention.

[Brad Hearing]

This is what a rubberized undercoating rust prevention looks like for a 2024 Sahara with 3000km on it.

I wish I had the factory bottom to show off as a before but sadly I didn't even think this would be a problem. Just like all of us, I did this for the same reason we do all things; it seemed like a good idea at the time. I did zero research and was in for something else like buying the goddamn thing but the cost was low and hey why not right?

Now lets be clear - I want to pick a fight here. Everyone else is all "blah blah blah not to be offensive" when they start talking but well the heck darn with that I'm going to be offensive by golly whether you like it or not if that's OK.

Alright. I get the job done and decide do to research which I'm told you should never do and instead trust the science but without even having the monitor turned on trying to search google I could see something was amiss.

Rubberized undercoating is basically what you do when you want to cover up problems or make something look good, say for an older 1960s car which would totally get you laid if you had one but you don't and its for the best because the only thing on the marketplace for these beauties is someones father trying to get rid of it because the frame rotted and he didn't tell anyone yet. Also he totally got laid in it all the time.

As for the rest of us losers its a bad choice; even if done perfectly rubberized anything dries out, rots, chips, gets hit by rocks (thanks for nothing, tires!) and traps water right where it needs to be if you hate your jeep - right along the [insert part you love here that was rubberized like the frame or in same cases the whole damn thing].

So anyway it turns out its not so easy to remove unless you like harsh chemicals all over the place where rubber exists, and so what you need is magic in the form of dry-ice coldness that freezes the crap off so it flakes off and......well magic! Now lets be clear... I'm not going to pretend i know what im talking about here. All I know is that the guy got rid of it then covered it with wax WHICH I DID RESEARCH BEFOREHAND THANKS FOR ASKING. GEEZ.

Now my garage smells like a goddamn beehive but that's only for the next few days which is good because I really, really hate anything that smells like a hexagon.

Here's the final pic, thanks for asking:

As you can see, some things are colored differently than before. I'm told this is a good thing and spent loads of money.

I applied Woolwax to the underside of my Willys. With all the salt applied on the road in winter, I figured it would hopefully provide some protection.

Our vehicles are undercoated every fall with a Biodegradable product called Krown. It prevents rust and corrosion and seals joints.
This type of product is a must if you live where they use salt or other chemicals on the winter roads.

Take your time to watch this i had this done at a pristine dealership.Alpha Cars in Boxborough Aa. Ceramic coating, ppf on front of hood around winshield and underneath fender flares and full wax oil under coat for rust protection.

I had the rubberized done to my 21 4runner as well. Just like you I didnt know much better other than knowing I wanted to protect it. After 4 years I had rust coming through in multiple areas. Who knows what was behind the rubber. When we got the wrangler, went straight for Krown and will be there yearly.

We’ve been using Krown on all our Vehicles since year 2000.. it’s done it job.

It looks good considering where you live. My advice for rust prevention is to move out of Canada, get as far south as possible.

I discovered Fluid Film when deploying helicopters at sea. It was used as a protectant against continual exposure to salt spray and did an amazing job at keeping our helicopters running for weeks and months on end. I later learned that Fluid Film was originally developed to prevent Navy ships from rusting during WWII, and is also used by NASA. I suspect there may be other products that are also quite good, but with that track record and my own first-hand experience, I can confidently say that Fluid Film is highly effective and will do an excellent job on your JL.

In b4 some dummy hijacks this thread and tells you that you should coat the bottom of your Jeep with AmSoil.
