Has anyone considered undercoating? My old (sold it) Ram 2500 rusted terrible underneath, it had a 4 inch lift and I was tired of looking at the rust all the rust every time I walked up to it.

Does PA use salt on the roads in the winter?

Salt, gravel mix it's terrible! My 2012 rusted in the first year (never the body panels just the frame, springs etc) I hope to keep the TRX longer than my 2500

He's right. I'm not far away and the sand mix gets into everything. PA also uses brine which is extremely corrosive.

Hey Don, 2 places I would check into. This summer, we had a Tacoma TRD Pro done at Elliots in Butler. He was very thorough and careful, doesn't drill any holes. They take things apart to coat. It's a father and son so no monkey messing with your new truck. His waiting list is usually several months long. He doesn't have a website but here is a link to his info.


There is also Schmidt's Rustproofing. He's maybe a mile north of 228 on rt8. No experience with him but hear he is good. He uses NH oil products. Elliot uses his own mixture based on our area.


Both are kinda oily, waxy. The stuff that hardens will eventually crack and allow that brine to creep in and rust away at everything. Just depends on your plans with the truck. Elliot somewhat protected our Fox shocks from overspray the best that he could. I would chose either over fluid film which I have on my truck. Any rubber that it touched swelled contrary to what they tell you. Did my doors and the seals got all warped and wavy.

Thanks I'll look into it. I can't imagine ever taking it off road but it will be my winter vehicle.

Once a month from december through march I wash my daily driver including the underside then roll under it on a creeper and fog the crap out of everything except the brake rotors with WD40. With all my years driving in the midwest winters I've never had any surface rust let alone had a frame or anything rust through with this method. It takes a couple minutes and isn't the cleanest process but is a hell of a lot cheaper than a supposed "lifetime" undercoating that is bound to fail at some point or another.

I live in salt country between Nov/Dec to March, and of the 6 vehicles I've owned in the past 20 years, now 7th with the TRX, I have never undercoated, simply because I perform all the maintenance on my vehicles, therefore, I like being able to get under my vehicle, do what I have to do, inspect everything without any visual impairment due to layers of oil,grease, etc., and still come out from under the vehicle looking clean. For those of you that work on their vehicles, you know what I'm talking about.

With that said, I've also never had rust issues (a little bit of surface rust due to paint chips on the frame, etc., but that's all) because I often wash the undercarriage during the winter months. On average, I'll wash my vehicle twice per week. Sometimes I'll go through the touchless wash, other days I'll go to the self serve and power wash the frame. It entails more time spent cleaning, but you appreciate it when you can work on a clean vehicle. Besides, undercoat looks like $shit IMO.

The RAM dealer offered to sell me their rust inhibitor package (wax type product?) for the TRX. No thanks!

@Brad1331 You said you FOG with WD40. Can you elaborate? Thx

Which is best?
CRC, I have also had great luck with it! The only downside is you have to do 2 coats, the final curing time is 12 hrs, but then even a pressure washer won't remove it, very good! Marine Grade!

Thats the can I use on WD40s website I buy it by the case off amazon its cheaper. I literally just roll under the vehicle on a creeper with some goggles on and spray everything down except the brake rotors it only takes a minute or so
