Detailing and cleaning noob

Sponges are a big no-no. It doesn't matter whether or not the sponge is new or old, it comes down to how grit is picked up by the sponge and has nowhere to go but be squashed down against the paint. It effectively acts as sandpaper, and buying a new sponge every time doesn't change this. Using a proper washmitt will help reduce new or heavier swirls being created.

Thanks for the information, Ed
