I have been speaking to Refectology from DW about S17+ in particular and it seems like a great polish, he even sent me his guide for using the Scholl Polishes. I read it all right now and its really seems like Scholl makes some amazing polishes and compounds. I knew what they could do and have seen the results pros have achieved with them before I posted this, but I never knew that results could be achieved so quickly with them. I became interested in them more recently because I am basically looking for a polish I can use as a one step for maintaing my black vehicles (both have hard clears) that can cut as good as 203s but finish down as nice as 85RD. I know 106FA is an option and I might go with it as well, but I think I might give S17+ a try. My question to those that use the product line is do you use the Scholl specific pads like the Spider pads, foam pads and waffle finishing pads when using one of their compound or polishes or do you use your existing pads i.e. Ubers, Hydrotechs, LC flats, 3M's, etc. I know the Scholl Orange foam pad and Waffle black foam pad are suggested to use with S17+ but the price per pad is pretty steep. So I am wondering is it truly necessary to use the Scholl specific pads with their polish to achieve a flawless finish with S17+ . If it is then of course I will purchase them but if not them I might just pick up one or two of each. Also does anyone use the Abrafix 125mm M14 Backing Plate, if so how do you like it?
