dewie,
Start here if you haven't read it:
MOTORCYCLE POLISHING 101 CLASS IS IN SESSION!
You want to match the grit of your sandpaper with the texture of the metal you are trying to polish. No reason to scratch it up and then smooth it out to where it was originally!! You don't not need to sand to anything higher than 320-400 grit. The Emory compound is about 400 grit! After you polish with one compound, change your buff and use the next finer compound, ALSO change the direction that you are polishing also, IE 45 to 90 degrees different. Clean your metal with Acetone every time you change buffs and compounds.
After you clean up your metal and it's fairly smooth just buff it with Emory on a sewn buff or a sisal buff, depending on the metal.
Did the gasket remover, remove the coating on your frame? If it's anodized you may have to use Easy-Off oven cleaner! Also try Aircraft Paint Striper if it's powder coated!
