tell you what i used turtle wax refine and shine clay, it's lubricant sucked the clay would stick to the paint. it was actually soap water, i poured it into a transparent bottle and showed everyone the jhaag it made, now that post is no where to be found,
then tried their liquid clay "it says safe for all paints" i read this and was comfortable that it would be fine for my single stage paint as it clearly says so, and tell you what, it dissolved it without even rubbing
