You've got two great products there but you're still missing the most important part that Rydawg brought up previously (A ROTORY) . In order to polish properly, think of it this way. Hopefully this will help you understand polishing more fully. When you apply the polish at first it looks thick, kinda like suntan lotion. When you apply it to the car it looks cloudy as you spread it. You need to use a rotory to generate enough heat to break down the polish so it looks clear by the time your done polishing. Kinda like there's a thin coat of vaseline on the surface. If you're wiping off the polish before it looks like this then you're probably leaving scratches from insufficient polish break down. I used a PC for two years before I got up the nerve to try a rotory. I never should have waited so long. I had spent so much money trying every product out there and what I ultimately discovered was that it wasn't the products that were preventing me from achieving awesome results, it was the tool I was using to apply them. Buy a rotory, even if it's a cheapo from Chicago Electric for thirty bucks. Keep the speeds slow at first and watch how heat plays a huge role in proper polishing. Don't be affraid of it. I learned how to use a rotory on my fifty thousand dollar black corvette and you know what? It came out perfect with no holograms, buffer trails or anything else! One more tip, use only a tiny amount of the SIP like the size of two kernels of corn and work in small areas. If you have any questions PM me.
