I agree 100% with FIRE UP. Do not use a grinder on your rig. I am a professional auto detail-er. If budget is why you would not want to purchase the right equipment then go to your local harbor freight or look them up online and you can find a random orbital buffer for like $80 with warranty that will do the job just fine. I wouldn't recommend their pads. Purchase your pads online at any autogeek.com, or chemical bros, their are plenty of choices online. If you are looking for a good all around product for wax I would recommend Meguairs paint reconditioning cream. If you have any other ?'s go to my forum @ www.promobileservices.net/rv-detailing.html#/
