A couple weeks back, I posted about having the undercarriage of my '03 LC sandblasted and painted with an epoxy paint. Several of you replied with warnings about the harshness of sandblasting so I heeded your advice. I reached out the to Mudder who referred me to the sandblaster and he did say that the blaster nicked a brake line and gas tank seam so he had to repair those, but he was still very satisfied and would do it again.

I figured I could always do the sandblasting next year so I scheduled an appointment with Krown at Davis Auto in White River Junction, VT. I've DIY'ed fluid film over the last couple of years, but I knew that I wasn't getting into all the nooks and crannies that I wanted to.

The only downside was the 2 hour drive, but I scheduled it on a Monday and we were at peak foliage so I just set the cruise and enjoyed the ride. Davis Auto appears to be a family run small repair shop in rural VT that sells cars, fixes cars, details cars, rents Uhauls, and applies Krown. They spray the Krown in a 2 bay garage across the street. They let me ride along to watch and document the process.

Once on the lift, Randy proceeded to drill holes in the bottom of the doors and tail gate. He asked me if it was okay, and I told him to do whatever he needed to do give me the best protection.

He then uses a long thin wand about 4 ft in length to spray the Krown inside all of the door cavities. Once he's done, he hammers the right size rubber plug into the hole.

Then he switches to a smaller wand with a 45 degree bend at the top to hit areas in the engine bay and undercarriage.

Finally, he finishes with a wide spray nozzle and goes over the entire undercarriage.

He told me that Krown uses a base of corn oil. It didn't have any odor and applied in a mist. It went on clear, but seemed to turn black when in contact with surface rust. It dripped for quite a while and I'm glad to have had the 2 hour drive home to let it further seep out.

It took him about an hour and a half and they charged me $129.95 and gave me a $10 coupon for next year. They also said if I referred anyone, they would give them $10 off now. PM me if you're interested and I'll send you the coupon.

Overall, I was very happy with the service and I hope an annual application of this will keep my rig's condition where it is today for years to come.

Thanks for sharing. How long does their coating last compared to fluid film? Is it also something that needs to be done before every winter?
 
@Kabanstva - I don't know how long it lasts compared to fluid film. I'll let you know how it holds up a year from now. Krown recommends an annual application.
 
@benjawi4 - unfortunately Krown is a Canadian company so most of their locations are across the border. They are making their way into the US, but most of them seem to be in NY with some in MI, OH, PA, and VT. I only know of the one I went to through their website. My father uses one close to him in upstate NY, but that's a 4 hour drive from me.
 
FYI, I had my truck Krowned in Canada three years ago and haven't had it done since. My frame still is absolutely rust free and there isn't a single speck of rust anywhere on my tRuck. I'll be having it done again this summer. This stuff works. I had to open my door panel recently due to a window smash and grab and the oil mist was still fully coating everything inside the door panel. Awesome product that absolutely works.

As I have mentioned in a couple of posts, I went to the New Hampshire Undercoating people (NH Oil Undercoating | "The Good Stuff!") and was very pleased with the results. They have developed their proprietary oil that they also sell, which rather than smelling like a sheep that has been thrown on a fire, has a nice cherry scent (like the Black Magic Tire Wet, for those familiar). They cost a tiny bit more $160? and recommend once a year application.
 
How well has it held up? Did it get tacky or anything? After i finally get a 100 (been looking for weeks!) i want to get it coated since it will see a lot of salt spray being a beach vehicle. I had minor concerns if the coating would clump up from sand being thrown off of the tires?
