Was reading a thread where someone Line X'd the undercoating. I'm in the Northeast salt belt but wondering if it's worth it on my preowned '16.

What has everyone used? Is using something rubberized make it harder to work on the truck for repairs such as removing bolts etc?

 

I had my 2017 Line-X'd and also under coated it but not with line X. On my 2nd winter and the underside still looks like new. Not sure what the lineX dealer used to undercoat but they did a great looking job. I'm also in New England... Connecticut and the roads are already WHITE with the crap they put down!! I feel good about having everything undercoated and the LineX dealer gives a life time warranty. I see any rust just bring it in and they will touch it up free..........

 

The only undercoating I would do is oil based (fluid film, crown, ...). It sucks to repeat the application but any hard paint needs to be perfect or the rust will concentrate in the flaws. When I say concentrate I mean it will rust faster in the coating flaws because the full galvanic potential still exists.

 

Roads around here are either white with snow or road salt.
I have used Fluid Film like product in the past. It was called OMC Fomula II. Oil wax based stuff work if you keep up with it.
I elected not to go with oil based coating, except in springs, shackles etc, due to dirt caking on the underside.
With oil based product, the sticky oil leaves a real mess holding salt, sand & dirt that does not clean up well.
I spayed bombed the skimpy factory painted frame with another coating or two of Rustoleum.
I must have use 7 or 8 large 15 Oz cans, covering outside and to a good degree the inside of frame.
In some spots subject to road spray, I also used rubberized undercoating as a top coat.
Finally Installed wheel liners in the rear fender wells and decent mud flaps.
I used some clear stuff to protect paint areas around the box steps etc. and bought this kit for the door sills.

Plus this around the wheel arch

After starts to rust, a bit, It will get an oil bath.type coating.

 

What shop did you use? I'm in Northern NJ.

 

I used fluid film on my 2015 the end of November 2015 when it was new. Reapplied it the end of October 2016, 17, 18. We have lots of salt and the new liquid they have been laying down. ( worse than salt ). Truck is on the highway most of the time. Winter is long and harsh here also. Truck looks like new under neath still. Actually better than new. The rear differential was really rusted when new and now looks better than it did.
This is the first time I have used fluid film and would definitely use again. My 2003 was under coated at the dealer and only lasted 2 yrs before flaking off and looking terrible.
Applying it was really easy with the kit I got on eBay. Pump it out of a 1 gallon paint can into sprayer bottle , connect to sprayer , hook up air and spray. Takes about 15 mins. Would be super easy with a hoist.

 

The shop I used is in Waterbury and I can highly recommend them. They do a great job as the owner is involved with every application. The only problem I see with their under coating is they require it to DRY overnight. Had a discussion with the owner and he won't do it unless it's allowed to cure for at least 12 hours. He's been doing this for over 20 years and seems to know his stuff. Anyway he's worth talking with even if you don't use his shop to do the application imo.

There is Line X near 287 Bound Brook area that does an undercoating, had my bed done there, excellent job.

 

Anyone else have an opinion or experience using Line-X for the undercarriage? I'm getting quotes from a few local dealers/installers.
