Hi Ralfy,
Well, it's hard to say. But Adam's and Blackfire were very close. Next was menzerna F400, the SI 1500 didn't do anything for me. I only liked the F400 because it took a scratch on my powdercoated rim using a wolfgang finger pocket. I was thinking about using the other products but I was experimenting. If the results are good, then I'm good. The wolfgang uber is next followed by the total swirl remover. But this is my ranking. It may be different with others because of the type of car and level of foam pad, microfiber pad, etc. I just got tired of all the different combinations and just wanted to narrow it down. I've read that microfiber pads work well, but for me I like the foam.
Hope this helps,
Alan
