Anyone doing it..? Krown or Rustcheck...or none...?

 

Did it last October with UniglassPlus Ziebart - Pentroil. They did a good job, been using them for years.

 

Did mine back in September with Krown. They have a good reputation and I cant complain so far.

My only issue is the drilling of the hole when being done. I have sprayed the bottom of car with the black stuff.

I had holes drilled in most of my older cars to apply rustproofing,no issues at all...it never rusted there..
If I remember correctly, the anti rust electronic devices are banned in Quebec....100% useless....

 

I remember seeing a video on these electronic rust devices. Some guy opened one up and found nothing more than a resistor and an led. Complete scam!

I don't rust proof the doors because I hate how the oil spills out and makes black spots everywhere. I've never had any rust on my doors. Rust usually develops on the rear quarter panels and fenders and on the underbody.

So I spray rubberized asphalt under and polish and opti-coat the paint.

 

I don't do Krown because the base they use is more liquidy than oil and drips all over my driveway and everywhere. Plus after a car wash or two, it's basically gone. Along with that, I don't like how they drill into your car.

I have my reputable mechanic (who is also my best friends parents) do it. They use the Krown stuff for hinges minor area's along the door and engine bay but they use this thick brown grease/oil gunk that sticks on the car. It looks hideous but it does an amazing job and I've been doing it yearly on every car I own.

 

I do Krown and it's great. The holes they drill are nothing and they are filled with flat plugs that look fine. The holes are the key to the protection, they allow the spray to get inside and protect the vehicle form the inside out. Watch what they do, they reach in with long thin nozzles and spray the internal sections that just could not be reached otherwise. It does drip for a day or so afterwards, so I leave my TL on the street for a couple of days and you'll see little droplets around when you park, after a couple of days the dripping is over. When I traded in my Accord the dealer walked over and right away said "you must get this car sprayed" because the car was 10 years old and there was no rust. When I got that Accord it was already five years old and that's when I started the Krown. I really believe in this product and will keep taking my TL in annually as long as I have it.

 

Guessing this is more of a North of the border thing??

 

Yeah Krown is a company that does rust proofing in Canada.

I still don't believe in the drilling the hole thing. How corrosion starts is when it's oxidized or exposed to air and salt. Even if you put the plugs, you're still drilling a hole which exposes raw metal which then puts air and eventually salt will eat around the exposed metal and get into it. It just seems to defeat the whole purpose.

Some may argue that it's to fill cavities that are inaccessible but it's more quicker to drill a whole. A mechanic who is skilled at rustproofing will be able to do the spots without drilling a hole. I just really don't like the idea of having a 40k car being drilled holes in to throw some dripping oil around so I opt for the hole free solution.

Krown also doesn't warranty brake lines, fuel lines, and gas tanks.
