What are the pros and cons of zylon coating for cars?

Answer 1

Xzilon (the correct spelling) is available for between $12 and $50 on eBay in a can that does three cars. Auto dealers charge up to $600 for spraying this on your car.

We have a car that got a full Xzilon treatment five years ago and it is indistinguishable from any other car of that age.

On application, it also got into all the cracks and crevices, from which it leaked a greasy, brown residue when it rained. Otherwise, it seems to be the equivalent of a good wax job. It did not dramatically extend the life of the finish, make the car resistant to chips, dings, pollen or bird poop.

After some dispute, we paid $150 for the Xzilon treatment, which seems like a reasonable price a) to get a very good car we wanted for only a little more than we wanted b) to pay for an extra polish we never requested and c) to find out our auto dealer was a cheating thief willing to rip off his customers by sneaking a "Xzilon treatment" onto the invoice at the last minute.
