Drilling holes has nothing to do with warranty and voiding it. It ruins the appearance of the car, and the holes are prone to rusting over a 10-20 year time frame. Just go through a junkyard and you can see what those holes like when rust get started.
Um, I disagree. In the Caravan you have seen above, which was 20 years old, had no rust around the drilled holes, and certainly would not have survived so long if such things had happened.
Also, who is really looking inside door frames for holes when looking at the "appearance" of your car. I mean this is really comical. It's not like they are drilling holes in the middle of your door facing outwards.
I guess you would have to get it done, or see it done to see the professional job they do, how easy it is and how well it protects the car.
Krown has been around for a long time and I don't think they would have grown as big as they are up here damaging/destroying vehicles. I mean look at what happened with Ziebart early on in their companies history and yet you still hear about it today...
I posted real world proof that their product works and causes no damage or accelerated rust to your vehicle as shown above with the new looking Caravan after it has been on the road for 20 years and 460K KM (287K miles) in harsh Canadian winters with extreme road salt.
Where is your proof that drilling holes and using them to spray causes damage to the vehicle and rusting around the holes, I would love to see pictures.
Just some food for thought.
