I searched for the answer, but didn`t find anything. Anyway, I put a layer of EX on the car about a week ago. Now I want to add a second layer to ensure even coverage. I haven`t driven the car, it has stayed in the garage the whole time. Should I give it a quick cleaning with some S&W before adding the second layer, or can I just go ahead without doing any cleaning? I don`t think it has a lot of dust on it, but I want to be sure I don`t accidentlly seal something in.
Thanks
