Hello, I am looking to detail my BMW pretty soon and I had a few questions about some products. I just purchased some poorboys ssr2 and ssr1. And also nattys paste wax. I think I am also going to order some EX sealant because I heard its good on black cars. But my question is, can I mix in some ardex products with the poorboys. Like I was going to use the ssr1 first then go to the ardex #2 polish for black cars. Or is the ssr a polish and I dont need the ardex #2? Im just not sure what I need. I also have ardex gold supreme wax that I was going to use as a sealant for now and then top it with nattys. Also can all this be done by hand because I dont have a PC and I have never used one before. I will get one in the future but not right now. Thanks everyone.
