dewalt is the best, I have owned a detail shop 4 10 yrs,u better get some assistance before trying it yourself. Check 2 c if there is an automagic dealer
in your area, they have great detailing products, pads waxs swirl removers ect.
Depending on the paint condition, if u want 2 do it right 1st clay bar the car,it removes paint defects,and gives u a smooth surface 2 work with.Next buy a
(depending on paint condition) product made from mequires called body scrub
used with your high speed buffer.Next look at paint,if swirls appear,use a swirl
remover, great product liquid ebony, used with high speed buffer.Next buy a product from mequires #26 paste wax works great,good luck if done right can
take a few hours.
