As an alternative to clay? I would love to decontaminate the Accords paint. There are a lot of those little hard small sap droppings on the roof, very small and only noticeable when viewing the roof at eye level. First of all, would clay even tackle such contaminants? I would just use clay, but if I understand right, it takes some time to clay an entire car, especially for the first time since the paint would be loaded with these contaminants. Also, I don't like the fact that clay will mar the paint, dragging those contaminants over the paint doesn't appeal to me. So is there a product out there that I could just spray on to get rid of water spots and contaminants...AND NOT HARM THE PAINT, as far as stripping the clear coat or what not. Up until now it gets a wash once every 1-2 weeks and a spray wax right after the wash. A paste or liquid wax is applied once every 3 months or so. It is outside 24/7 in the Florida elements. Lots of direct sun, and its parked under a tree from 6 PM until I go to work in the morning where it sits in the direct sun for 9 hours. Paint is desert mist metallic (Honda paint color).
