If you’re operating from a SMART repair cabin and have no additional prep or polishing bays then using cordless or air powered operated machines is the only solution due to the mandatory legislation of no electrical source of power to be used inside the spray cabin.
The Makita cordless polishing machine fulfils this legislation and is remarkably adequate in both detailing and paint finishing polishing requirements.
It has both random and orbital rotation modes which is superb for the appropriate task being carried out and leaves no swirl marks (most often occur when polishing darker colours).
The 5ah battery lasts approx 30 mins, more than enough for specific polishing jobs. Having more batteries to hand already charged is a bonus.
