So now I am here, considering it.

I know that the wax based solution from them involves no drilling, and has a lifetime warranty, which is good. But I'm debating if its worth it. Here is my situation:

- Drive around 25000 kms per year, and will be driving the car all-year-round.
- Live in Thornhill (Vaughan) and commute into Toronto every day, so plenty of salt on the roads for sure.
- Planning to keep the car for a long time.

I know that the cars come from the factory with an anti-corrosion coating on the underside of the vehicle, and that the body panels are dual-side galvanized steel. (Check here for reference, click on the Exterior tab) So, should I even worry about any kind of undercoating at all? I've often heard that regular washes at a touch-less wash with the undercarriage spray (around twice a month) will help with keeping the car minty.

Krown is out of the question because drilling holes throughout the entire car is no-bueno.

Thanks!

You actually answered yourself with pretty much my stock reply. Modern car are not the same as a 1982 Omni that will rust away in 4 years. All car rust eventually but ours will take a long long time as is.
