I don't have trouble applying SG. I get a little bit on a MF bonnet and apply it between speeds 4 and 5 on my PC. Do not use a lot! A few drops will do the average door or trunk lid. I do one panel at a time and buff off with a MF towel. If I do get some streaking, it's usually very minimal and some QD removes it no problem. I might try AJ when I run out of SG (in the distant future). The only problem I had using MF bonnets to apply AIO and SG were that they cake up pretty quickly. I went through 2 bonnets (double sided) for each product.
So yeah, if anyone hates AIO and SG so much they're gonna chuck it, send it to me instead!
