I have the OptiCoat on my 17 Raptor - put it on about 3 weeks after i bought the truck. So i can tell your first hand what its like to wash the truck before and after the coating was applied.
It's a night and day difference in how long it takes now to clean the vehicle. I live where we have extremely hard water, leaving water spots everywhere. Those are a thing of the past. Now when i wash the truck, i use a couple of cap fulls of the fancy OptiCoat no rinse wash, two buckets and a sponge. Take about 20 mins to do the whole truck, and the truck is MUCH cleaner to start with. The coating really keeps a lot of dirt etc off the truck in the first place so its easier to clean.
None of these coatings are cheap. Who really knows how long it will last. It's going to get tested for real this weekend on my first Arizona Raptor Run....
