"I have used a grinder buffer
"I have used a grinder buffer with 10" pad to apply 3M Perfect-It II Rubbing Compund liquid for medium oxidation. You can also apply it with an orbital hand polisher if in small spots or high reaching is required. The final process is 3M's Perfect-It II Finishing Glaze applied with a foam disk or hand applied with foam wax applicator. No wax is required after that but for added protection you can apply a Carnauba Wax yellow #2 grade. You'll be set for a year and very little if any return of oxidation. The key is once you compound, rub, scrub a gel coat you can leave fine scratches that will allow oxidation to form again once wax applied start to fade. The glazing helps retard that. Give it a try, I doubt you will be disapointed."
