Rust Proofing

[brandon_guzzo]

I am having my new silverado under coated for the first time this year with a krown no drip formula and was wondering that after it has been rust proofed should i still wash the under carriage during the winter? I wash my vehicle about once or twice every two weeks int he winter and am not sure if washing the undercarriage will help prevent the salt from forming rust or should i just leave it. Also i would like to know whether or not it is better to park truck in the garage or outside again t help in preventing rust formation. Thanks for all the responses in advanced

p.s i live in the rust belt area of toronto

I usually do not wash underneath at all, this includes inside wheel wells for atleast 2 weeks, normally 1 month. Lets the oil 'bond' to everything better.

 

We use the Krown original formal, drips, but who cares.

I ve heard guys say to run it down a dirt road. That will coat everything and dry it up.

I have been getting the oil spray from Krown for a while and have talked to the owners. Driving down a gravel road is bad because the dust sticks to the oil and absorbs it. Letting the oil properly cure into the metal is crutial. Washing the underside of the vehicle with high pressure water is not recommended because it could strip the oil preventing it from soaking into the metal. I washed the underside of my truck previous to getting the oil spray with high pressure water to clear the dirt off so the oil would have a clean surface to adhere to. The process will drip for approximatley 1-3days after application depending on temperature etc...

 

Hope this helps

I Krowned my truck a couple of months ago and honestly didn't even notice any dripping - although I don't have a paved driveway. I'd say the dripping is very minimal.

 

Krown all the way!

 

Back on topic - I wouldn't wash it right after, like others mentioned. I've pressure washed the wheel wells about a month after and it didn't seem to matter at that point.

ive heard of this a couple times but where can you get something like this done? or is it DIY

I believe it all depends on where you live DM?

Krown and Rust Check are very popular up here in Canada and I would assume the Northern States?

Do a google search on both of those mentioned and see what is available in your area?

 

I have rust proofed my vehicles for at least 25+ years and it is bar far the best solution to help combat or stop the rusties!

 

As far as washing goes, I have always sprayed water underneath my trucks, especially in the winter to get the salt off,, it does not remove the Rust Check or Krown but use some common sense and let the solution "cure" so to speak before doing so.

I think a week or so is sufficent but if you haven't driven in any salty soultions don't worry about it until you have.

I also, after it is sprayed and a few days have passed, drive down a sandy/dusty road, this helps the solution stick to the metal and provides another barrier against rust.

I have been doing this for 25+ years as well and my trucks/vehicles have never shown any signs of rust except for the high wash areas that come from the tires.

In that situation, I just buy a can or 2 and do some touch ups every so often.

With the EPA, some of these sprays aren't available in the US. I used Fluid Film on my truck last year and just hit it up the other day as well. I also sprayed my snowthrower last year and the underside of the mower deck this year. It seems to work nicely.

Hey Bill,Tell me a little more about this "Fluid Film" Do you spray it,or brush it on? Does it dry clear and hard,or is it tacky?

The local John Deere dealer here has it,I saw it in there the last time I was in there,I just didn't know what it was.

If you have had it done once, then all the plugs will be in the doors, etc. And if not, no biggie, you can do it yourself.

 

Here is the GUN we use. Works great!! We made a wand out of brake line, and brazed the ends on to it. Works better than the hose.

It dries clear and you spray it on. I had a shop near me last year spray it on for me. This time around, I again bought the cans, but went to the usual mechanic I go to who allowed me to spray the truck using his lift for free. It just leaves a bit of a residue where you can tell something is on there. At least that's how it was when I did the spring oil change. I grabbed the cross member to roll myself further under on the creeper and it had a grease/oil type feel on my hands. I just bought a few cans each time to spray on, but I believe they sell in larger quantities too.

my friend had suggested me to coat the surface of car body with metal primer where ever their is an expose. and it did worked well. would suggest same for others

[lisathomas]

Yeah i think you should wash it under the surface...as during winter you should be very careful before washing...i preffer to give my car to the service center...they know very well how to do it
