When buffing your car I have seen that some have a halogen light with them so they can really examine the paint and look if the swirls/scratches are gone. What is a good light to get? Can you put the light up to the paint in the day? I seem alot of them at sears. What does everyone have? A stand one or a portable one you hold. Like those ones that you can hang on something. Is it neccessary? Here are a few links, there are alot more, but you get the point.
