where do you get these clay bars/clay bar kits at? and also is it applied in the shade or can you do it under the sun? would the outside temp have any kind of effect on the overall apperance etc. etc.? got nothing to do this sat/sun and it's gonna be nice and sunny high 70's - low 80's. oh yeah after the clay bar would it be a good time for touching up nicks in the paint? gotta go to work peace b.
