BMW Rust Warranty sucks. They simply send it to a shop to grind it down, and paint it. It comes back. I had my E36 done under warranty, and the rust came back. They should have replaced the two doors, and the trunk, but wouldn't.

It was a pissing match to get the warranty done.

Like everyone said, Krown is the way to go.

Wait, they drilled holes on the outside of the car? That can't be right.

On my car they drilled two or three holes in the door jambs (front & back), then a couple more in the trunk well. I'm sure there are probably more, but I didn't search for them, they were just the ones that were obvious.

And from what I remember Krown does offer a warranty. If you start spraying a car from new, then they give you a lifetime warranty. They obviously won't warranty a 10 year old car though.

The holes drilled should be on non visible areas (from outside).
The door jambs, rear dog leg etc.

I always carefully pull the plug they install afterwards, clean the hole, and put a bit of primer/paint on the newly exposed metal edges of the hole. Once it's dry, I put grease or more Krown/RustCheck stuff on the plug and push it back in.

It keep the water out and is protected.
You won't have any issues with the hole after that.


Actually, if you ever install a spoiler, or trim/skirt pieces, and have to drill small holes, do the same.


If anyone decides to do a DIY for their window regulators, a can of RustCheck or Krown should be part of your parts list.
When you have the door panels off, spray into the bottom of the doors from the inside.
BMW's rust at the seams, and this will go a long long way!!!!

No... apparently there are 2 techniques...
Drilling holes and then just spraying the exterior.
They say drilling holes gets the rustproofing liquid into hard to reach areas.

I am not crazy about having holes drilled into my car too...
But then again... I don't plan on having my car for more than 6 years either, so a few holes (properly cared for) might not matter either.

If I have to chose between having a few holes drilled in inconspicuous places, or rust perforation in obvious places, without question I chose drilled. Seams are where you're going to get rust most often (accident repairs aside), and there's no way of getting inside those seams just by spraying the outside of the car. In my opinion the shell is the most important factor for resale. Engines and interiors can be had a swapped for relatively cheap and work well. There is however, no such thing as good body work. If it's been fixed, it'll need to be fixed again...and again...and again.

I got my car rust proofed at:

Krown Rust Control
1019 Lakeshore Road East
Mississauga,ON
(905) 278-2408

They are a Greek family owned business they have been doing it for years and years. They have the best reputation of all Krown locations in GTA since they do an excellent job of rusting proofing your car and you can tell them you don't want to drill holes in your door jams and just spray the car underneath, hood and trunk, taillights, door handles around the windshield rubber etc.

I know that RMP(one of the vendors on here) undercoat without drilling i beleive. I'm not too sure what product them use, but maybe worth calling them up!

I myself wouldn't want to drill holes either, but there's always alternatives.

What exactly is BMW's Rust warranty? My 02 330XI, has this spot right here. It is a lot worse looking now than in that pic. I am not the original owner of this car, so they would fix this for me?
Also this Krown stuff is this very oil based? Almost greasy looking?

i haven't rust proofed my M3 since i had it (over 4 years) and winter driven it every year.
when the weather warms up, i make sure i get a wash and get the underbody washed also.
i've only had 2 rust spots (1 of them was just cleaned up this week) and both were just below the driver side and passenger door sills. about the size of a toonie. my e30 i rust proofed every year when i had is and it rusted a lot quicker.

imo, i'd vote against having any drilling done on the car. but the important thing is to get all the salt off your car when the weather is warming up in the winter. salt starts eating away when the weather gets warmer and is when it does it's most harm.
clean car = healthy car. wash and dry it often and you won't get rust attacks.
