wetness around axle

Now compare that to the pic I took while underneath my 2015 greasing the U-joints. And its been through 9 salt infested winters.. Gets Krown sprayed every year.

 

yeah man, that looks excellent. nice and dry and smooth

 

Actually not dry at all .Everything has an oily film on it...

 

oh ok, then much thinner than the tarry undercoat

 

Never used and never will use undercoat. To me it has no value as a rustproofing and in fact can make things worse.Eventually it will dry and crack and then water and salt can get between it and the body. So the cancer starts and the undercoat hides it. I call it a sound deadener and nothing else.

 

what you're doing is clearly working. I'm confused at the difference between Krown and undercoating. I've seen the terms used interchangeably

 

Traditional undercoating is a rubberized substance made of materials that include fiberglass, ceramics, rubber, asphalt, and silicone and forms a thick layer on surfaces.

Might not be exactly the same but you have probably seen the spray in liner you can get for the beds of pickups.

Krown (rust check etc) is basically a thicker version of WD40 that is sprayed on all the surfaces leaving an oily film. What I especially like about its application is that it is also sprayed as a mist inside the doors etc. This lubricates all the locks, window tracks, electrical connectors etc that never see any additional lubrication beyond what is applied at time of manufacture.

I have been using it yearly on on my vehicles for almost 30 years now. I had a 1982 chevy Monte Carlo which had the traditional Ziebart/Superior style of rust proofing which was a wax like substance sprayed in the doors. This ending up drying and cracking like undercoating and then trapped the water /salt under it and within 6 years my door seams where in bad shape. A friend had a 1976 Monte Carlo (6 years older) who used Krown and his car was rust free. At that point I switched to Krown and never looked back.

Its also heavier than water so it gets into all the door seams and displaces the water making it rise to the surface an evaporate.
If you have water in the door seams in any place where you have freezing temps it can freeze and exert 43,000 lbs of pressure and this can cause that seam to split, pop welds and crack paint. And this water can just be from the condensation of moist air on the cool inside of the door panels. Repeat this every year and you can see why the door seams are the first to go.

This is a picture of the bottom of the door seam on my previous 13 year old honda odyssey. It had been through 13 years of Toronto winters and the salt and brine they use for deicing. The picture say it all. 100% rust free. And that was the same for all the seams including the rear hatch.

Its cost me the same as one tank of gas once a year but is well worth the cost.
I consider myself mechanically adept and have done minor and major repairs myself and all my own maintenance. But i would never want to deal with the results of body panel corrosion.

With the ever increasing cost of vehicles now statistics indicate the average age of vehicles on the road is up to 14.4 years. I want mine to last even longer.

And no I do not own a Krown Franchise or own stock in the company..

 

hell yeah, you're basically a walking ad for Krown haha. Thanks for the insights. I live in the south so I don't deal with salt, etc, much, but this is definitely helpful in finding the right tacoma

 

And to prove that last picture was not a fluke, here is the seam on my 2015 Tacoma. Seen 9 Toronto salt infested winters so far....

I don't need to be a walking add for Krown, I just show people the results and let them decide.

Neighbor had a very old honda accord. Rusted so badly that while parked in the driveway all the shock towers collapsed and it fell to the ground. Even after that they bought a new car, decided against Krown and its already showing breakthrough rust on the fender wells and lower door seams..

If i lived somewhere where temps are never below zero and you never see salt I would still get this done maybe once every two years just for the lubricating properties of all the inner door components.
