You're probably going to get told by those more Autopian than myself to blot. HOWEVER, as for myself, I have no worries about Big Blue scratching the paint; any morseo than I do about removing wax with the other microfibers. And yes, I have 1000 watt halos in the garage, and I've checked for scratches after/while drying. None to date. Mebbe I'm just lucky.
