I have a 2008 jeep wrangler that is black and has some oxidation on it that needs to be removed. I just got some menzerna compounds starting with the 400 then 1500,2000,3000 and 4000. I am hoping to start with 2000 but will have to see what will do the trick. Then going to apply a sealant then a carnauba wax. I have both a rotary and a da and want to know if I should start with the rotary to make paint correction easier and then move to the da after the oxidation is removed. What do you guys recommend. When do I use the rotary and when do I use the da?thank you for you advice.
