Yes, they recommend washing using the 2 bucket method, especially within 24hours if there's stuff like bird droppings, and need to visit once a year for inspection, which is not too bad (http://sierraglow.com/after.htm). Nothing about claying, unless you mean I will still need to do that myself, which I guess I probably will not. ONR looks interesting, I'll take that into consideration. Where can I purchase bottles of ONR? Still leaning towards glowing the car though, as the hydrophobic layer is supposed to last about 1 year, and shine for 5 years >.< I'll wager it's an exageration, so I'm still looking for long term user reviews.
