Thanks DavidN. I can attest to the SG application and approval method you describe. Using one wet and one dry does end up leaving smudge marks. Definitely wipe on, then wipe off works the best. I learned this lesson pretty quickly on jet black. As for the AIO, my car being brand new, I just did one pass of AIO, and that did plenty of cleaning.
