I recently clayed my car and what a big difference claying makes!!!
Here's a tip (if this has already been posted please delete this thread) to find out if claying has removed contamination in the paint:
-Get a cellophane (the cellophane that comes with cigarette packs is the one I used) and wrap it around your index and middle fingers.
-Move your cellophane wrapped fingers along the areas where you have clayed and to areas where you haven't clayed yet. YOU CAN FEEL THE DIFFERENCE! And you can actually feel the paint imperfections prior to claying.
