thats the claim but let me know how that works for you because the stuff I use forms a hard waxy shell like what waxoyl states and it gets blasted off in the areas I mentioned. It doesn't need to be reapplied yearly but it needs done around wheel wells at the very least.. also I said its similar as they both use wool oil actually project farm did a video on this and his results were interesting none of the mentionables did as well as some others not mentioned here.
Researching this myself theburtman I haven’t heard of that brand I am leaning towards the New Hampshire spray; not right name. Family that plows says it keeps rust away for about 10 years Here that is 399 for a truck. It you carry calcium chloride in your truck as they do that says something In the Pines can you link video?
I used some of this stuff mid 00's. Got a gallon through work. Application was messy but it stayed put for almost 4 years. FWIW the Tacoma that it was on was one of the last 'frame rot' claims done by Toyota in my area. I did not reapply after the first time. I believe it was developed to combat flash rust in machining applications.
We get our two daily drivers done every year at Krown. $140ea. Nice thing about Krown is all places have to go through a training process and are backed by corporate. Both of our vehicles are '21's and we've been having them sprayed now for 5 years, starting when they were brand new. The underneath of both have zero rust. Even the suspension bolts don't even have rust on them.
The NHOU website says it should be reapplied annually. Not what I was looking for. Anyone remember Tuff Kote? I had a vehicle they did. It was like the underside was armor plated.
How long did you own the vehicle afterwards? Did you ever have opportunity to get under it and work on things, or poke around enough to verify that the coating was indeed 100% intact, no rust happening underneath the "perfect looking coating"? That's been my experience with any coating that "dries"...water/salt works its way in and goes to work underneath unseen (for a time)
I didn't get under it a lot, and actually only had it about 5 years. I figured there must be something wrong with their product/service or they would still be around.
Zero experience with their undercoating but I must say that I dried off thousands upon thousands of cars at my first job. The slickest paint to ever roll through our tunnel either had Liquid Glass, or had a Ziebart sticker in the window. I have heard the horror stories. I'm telling you whatever they put on those cars paint way back then was absolutely mind blowing. And yes I can still remember the worst finish I ever dried....late 70s Ford Galaxie coupe with white paint. It's bad when you have to pull your towel across rather than push them. It was a regular for about a year. I've never used Ziebart and don't endorse....but man...the finish on those cars has stuck with me. Usually an older couple in some sort of sedan.
Ziebart undercoating...I have zero experience with any of their other products...but based on my experience with them on that, they get a big thumbs down...their "warranty" is meaningless when it comes down to it...
I think you are going to find that the one time application types either don't hold up, or end up doing more harm than good over the long haul. The good fluid types of treatment self-heal and are all annual applications.
Usually a touch up annually; which is usually less $$ you can definitely tell when it’s on a lift where it’s worn off. uncle with plow business said he gets a deal BUT he does at least 10 vehicles a year. Also depends on miles and road conditions
