YUP you sure will
I have detailed cars for over twenty years. Orbital buffer is best for waxing and you will get out very small or light scratches. DO NOT Lean on buffer! Stay of edges. Do mirrors by hand. Depending on what quality of a buffer you get or use you can Burn through the paint. Rip windshield wiper arms and blades off right along with breaking the plastic window vents people add on to their doors.
Do try using a little water "MIST" like from a spray bottle the wax will spread evenly and use wax and water sparingly when you apply it to the paint the buffer will sling it every where.
Using the mist of water is only after you get the pad or bonnet full of too much wax or a build up of wax in the bonnet. Do not use wax and water at the same time
If you want more tips or this is confusing JUST ask I try to explain this to you in more detail.
