I usually apply in shade or away from direct sunlight to a clean surface(though 303 itself can clean, you are just wasting product since soap/water can do the cleaning job for most apps)...
Anyway, what I typically do for plastics, vinyl or rubbers is spray it on(try to control it from running everywhere or where I dont want it), and wait for 5 minutes. Then I wipe reasonably dry, not hard scrubbing though. Turns out nice and lasts through a couple rain storms, but not many so far from my limited experience. Nice thing to do for your car while cleaning it, anyway, and another product that can help clean before 303 and a restoring product after it, in combination would make 303 go longer, IMO. Not sure of the product I have in mind off hand at this hour.
FWIW.
