Hi Gregar
Regarding the discounts on the Opti-Coat, ZAS is just the supplier of the product to the dealer. We don't currently offer the actual service.
Application time will vary depending on how much prep work is required. For a brand new car with flawless panels you can be in and out in half a day. If machine polishing is required you would expect to lose the car for at least a whole day, possibly even have to leave it overnight if there is a lot of work to be done. Opti-Coat is touch dry after 30 minutes and fully cured in 12 hours. No water during this time, so that is another thing to consider if its raining. You would keep your car at the dealer until it is cured before taking it out.
We are just in the process of finalising a warranty for the Opti-Coat. Everything will be complete and up and running within a couple of weeks. Like all other paint protection plans, you should contact your insurance people and have "paint protection" put on your cover. If you have an accident and it needs to be reapplied, the cost is covered with your insurance claim.
On that topic too, Opti-Coat does not cause any repainting issues due to the prep work that is involved beforehand. I had all this info somewhere on what the painters do beforehand and why Opti-Coat wont cause any issues but can't seem to find it.
