If you find anything fitting that description, please post back. I was not successful in finding anything that convinced me would apply well without much preparation. All painting is much the same - the effort process amounts to 75% surface preparation, 25% application.
Yes, there are ceramic beads in Bus Kote, but I think that portion of the product, and similarly-marketed products, has been proven to be a form of snake oil. The heat-lowering capacity derives from its albedo, not from any "secret sauce". I knew that when I bought it, but snake oil aside, it was clearly formulated for automotive roof applications and that's why I chose it.
I did a light overcoat yesterday using a four-inch paint brush, and my slightly-dulled roof is back to its former blindingly-white glory. But as I noted in the blog post, at the manufacturer's recommendation, I opted to leave off their clear top coat so that I could do this kind of touch-up work routinely. It's not hard. This weekend was wax time, and brushing up the roof is really not more difficult than applying and buffing wax.
