Almost any buffer can be used, I have the Makita 9227C, use the polishing pad..not the wool pad, set the buffer on the lowest speed. Use a paint brush to spread small amounts on...then spray..mist with water to keep it wet. It works wet...does not work if it gets dry. Buff away...wipe excess off with towel...Seal your new wet look shine with a quality wax.
BTW, its the best I've seen or used...I have a pretty new boat so I use the 2000.
Hope that helps.
