Krown Rust Control Damaged Plastic and Rubber Parts
ale...@yahoo.ca
Krown rust control for about 16 years, the first one was Mazda 323
1988, it is true when the car was scraped 1n 1998 as the result of the
accident it was very little rust on metal parts, but bumpers where a
mess, they have been warped and I had to replace engine mounts in 1996,
because they where completely melted.
Unfortunately I did not realize the cause and effect of this problem
and continue Krown service with my 1998 Honda Accord, and what a
surprise, surprise after 7 applications a number of plastic parts begin
to exhibit the same type of damage as bumpers on my previous car. When
I attempted to point this problem to Krown, theirs response was that
their records indicate no such problem, and the only liability they
willing to accept is 2 rubber gaskets under the hood, which Krown
willing to replace, moreover if I choose to continue to spray my
vehicle, no further responsibility will be accepted.
The total amount of parts to be replaced is about 1000.00 dollars not
including tax and according to my mechanic it may take up to 10 hours
of labor to replace.
So at this point I am not sure what is worse the cure Krown Rust
control or the decease rust.

People need to be smart enough not to spray rust proofing on plastic
parts. At least the material can be cleaned from the plastic parts to
prevent damage. And I don't think you have proved the case that this
product is causing your problem.
William R. Watt
If it is a problem then perhaps the rubber and plastic could be masked,
sealed, or painted to protect them. Spray paint or undercoating might do
it.

I have researched this in the past when I wanted to rust proofed
my RSX (acura = honda). I found that indeed, it is well known
that the light oil from Krown, Rust Check, and even Metropolitain
Rust Proofing distord and extend the plastics and rubber seals of
certain japanese cars. While you will most likely get testimonial
to the opposite, I have seen it myself with my own eyes on a 1999
civic and 1991 integra. Also, check out the web site from
Metropolitain Rust Proofing (see the French Forums), and indeed,
people complained about this in the past.

This also caused some electrical problems for some people.
Metropolitain told me (as well as Krown, btw) that if I am
worried, they could paste some silicone gel on the rubber seals.
However, I never went there because of this fear.
I did rust proofed my RSX, using oilguard and thicker grease/wax
based product. Apparently it is safer then the thin oil for the
rubber. I do the rest of the doors and quarter panels myself.
However, I think I will be rust proofing the car only every
second year, for now on. New cars are made better now and do not
rust as much as they used to.
I am amazed that Krown is not honouring their products: they told
me that this was a possibility. Go to small claim court with your
mechanic.
Good luck

Where I'm at, 16 years of sunlight and ozone will eat the plastic and
rubber off of anything.

It depends on the materials. Acrylic plastic and EPDM and silicone
rubber are inherently virtually impervious to them, and other materials
can be made highly UV and ozone resistant. EPDM rubber is used for
radiator and heater hoses but can be severely damaged by certain oils,
including motor oil. Neoprene is used for vacuum and fuel hoses and is
resistant to motor oil but is known to deteriorate from sunlight and
ozone.
Chemical resistance information for various materials:

Not likely to happen on the underside of a vehicle where the sun don't shine.

was performed by Krown personnel in their head office on 245
Creditstone road and in this case there are 3 issues that are
important:
1. Krown compound is fatal for rubber and plastic parts on both my cars
2. Sloppy application that allowed compound to be leaked on this parts
3. Krown treatment of the loyal customer, who brought the problem to
their attention
Moreover, this is just the beginning; it is my intention to prove
number 1 beyond reasonable doubt.

Ozone is everywhere.

A great deal of UV is reflected off the driveway, and shade reduces the
intensity only by a factor of 4-5, less around the perimeter.
Identical materials under the car have been known to fade or
deteriorate noticeably more than those inside the engine compartment.
William R. Watt
I was referring, of course, to sunlight.
I suppose if the particular rust treatment acted as a catalyst then ozone
could be the problem.
