I just used SG on my car today and didn't have any problems, that is after I altered my process. I had tried using a yellow foam applicator but still couldn't get it thin enough. I decided to see what the PC could do for me. Last week, I got the Sonus SFX pad set from Autopia. In the kit, there's a set of two buffing bonnets. Using the Blue SFX pad covered with the bonnet, I lightly coated the bonnet with SG. With the PC at speed 3, I set out applying the SG. It went on so thin and evenly, I couldn't believe it. But the true test came when it was time to buff it off. With my trusty PakShak MF in hand, I gently buffed off the reside, and guess what? No streaks! Wow! It worked like a charm. A quick spray of Sonus Acrylic Glanz and I was good to go. This is by far the easiest SG method I've tried to date.
