For 3 years now, I've used the Krown undercoating for our F150. Three
years ago, the truck slowly dripped the undercoating for several weeks.
And I was advised not to park it on pavement. The truck was parked
partially on grass and on the street.
Last year, I went back to the same location and had it redone along with a
salt eliminator wash. When I got the truck home, I parked it as I did the previous year.
The following day, there wasn't anything dripping off the truck anywhere. I called
the place and firmly talked to the manager about the situation and brought the
vehicle back the same day. After 45 minutes, I left the place and sure enough the
truck slowly dripped for weeks. I even inspected the truck on my back with a flashlight.
Good job.
I didn't go back to this dealer because of their shoddy workmanship. I went to another
dealer this year. While I talked to the manager and installer. I explained to them in detail
the reasons I was there. Because of their policy, I couldn't go into the shop and watch
the salt eliminator wash along with the Krown spraying. After I got home, I parked the
truck and closely inspected the under carriage and such. It dripped for several days.
I'm not sure about the salt wash because there is road dust accumulated and the Krown
spray does get absorbed into this and is very wet. I thought that the wash was done with
a power sprayer. Does anyone have any feedback on Krown's process for the wash or
anything else for that matter?
Thanks,
Kellsey

 

Kellsey -- First and foremost welcome to the forum!! You'll find lots of great information and people on here.

Krown should be reapplied every year to keep the Krown warranty in tact. Whether or not you choose to do the Salt Eliminator is entirely up to you.

I just started doing Krown treatments on my new-to-me diesel truck after doing a ton of research and comparing it to other products such as Ziebart. I can confidently say that it really is good stuff and I'll recommend it to anyone looking to preserve their truck from rust.

My Krown dealer in my area actually has a few windows out into the shop and you can see exactly what the technician (in my case, the owner) does. I chose the Salt Eliminator wash and then he drilled access holes in necessary areas to spray Krown into. He also went through all hinges, lights, etc and made sure it was well coated with Krown. They sprayed it on nice and thick, and it took a few months for it to actually stop dripping.

The Salt Eliminator wash at my Krown location was done with a pressure washer with foam cannon. He then thoroughly pressure washed all salt and grim under the truck. He then applied the copious amounts of Krown using a high pressure specialized wand from a bulk container of Krown undercoating.

Because I live in Upstate NY, and the city I primarily work in uses 100% salt I do my truck twice a year. Once in the Spring with Salt Eliminator then Krown, and once in the Fall with just the Krown. I keep it parked in my garage on a concrete floor and don't care if it drips. For the price, it's well worth it having it done. Plus the Krown shop I take it to, I don't need to schedule an appointment. I just come in and they do it -- works way better for my active lifestyle.

And for what it's worth, I love the smell of Krown. I couldn't get enough of the smell when I was out in my garage.

 

ManualF150, so what your writing is that the Salt Eliminator is applied and power washed off.
If this the case, I paid for it and this Krown dealer didn't power wash it off even though they
claimed they did. This is the matter of contention that I'm discussing. Underneath our truck,
the frame and its components have a thick layer of road dust. The truck dripped the Krown
undercoating for a few days after the third application. Where the other 2 yearly applications
slowly dripped for a few weeks if not more.

 

Yes, he sprayed it on the with the foam cannon and then pressure washed it off after letting it sit for a few minutes. Krown Salt Eliminator is a detergent that neutralizes the salt in hard to reach areas.

I just found out that Krown actually has a website dedicated to it's Salt Eliminator: https://www.salteliminator.com/ -- Go check it out!

You have two options. Contact Krown directly and speak with them or find a different Krown dealer. Maybe they didn't get trained properly, was in a rush or what not.

As far as it not dripping as long as the first applications likely has to do with the fact they didn't spray it on as copious as the first time.

My local Krown dealer does a fantastic job though. Very thorough job.

 

Okay, that clears up the Salt Eliminator application for the exterior sheet metal part of the truck.
It makes more sense with the video. The Krown Rust Inhibitor is applied over the road dust
that collects underneath the entire truck. Also, the road dust isn't washed off prior to the newest
Krown Undercoating for that season.

 

The road dust actually helps the Krown stick better and hold. That is why the more times you Krown, the better the protection over time.

I was able to collect some in a little dish, because my Krown dealer put a lot in my running boards. I tested it out on some cleaned, untreated weldable steel that likes to oxidize, and no oxidation when left outside. Not sure what is in that stuff, but it's simply amazing the chemistry.

Is it good for the environment? Not sure, even though they say it is. But in the long run my truck will likely never rot out.
