I bought a new car in December and have washed it weekly since then and applied some Nufinish for some protection, this was before i got into detailing. I bought a PC buffer and all the waxes and sealants I should hopefully need to give it a good detail when I get a few days off work to do so. I bought a Mothers clay bar kit to use on it. Will the Mothers work for this? I didn't know at the time of purchasing it that there is different grades of clay bars. The paint doesn't feel real smooth after washing so I'm guessing that it needs clayed. Also I've read of people saying that claying caused scratching. Is that a possibility? Currently I don't have any swirls or anything that would call for polishing.
