This will always depend on the finish you’re looking for, the effort you’d like to put in and the time you have available because you can get great results using either method. Rejuvenate Paintwork Cleanser has been developed using advanced diminishing abrasives which are designed to be extremely easy to break down by hand, so it doesn’t require a machine polisher to work the compound all the way through. All you need to effectively clean away oxidation and hardy contaminants, along with lightly refining paintwork, is a Microfibre Applicator or a Polish Pad. But that said, when you’re looking for the most consistent, professional finish over a whole vehicle, using a DA machine (such as our DPX or MPX Dual Action Polishers) can be the easiest option. Machine polishers will apply the same mechanical action to every panel for the ultimate constancy, and they will certainly take out most of the elbow grease. When using a machine polisher with Rejuvenate we recommend utilising a suitably soft, Revitalise No:3 Refining Pad for 5-inch polishers, and the equivalent (red) Revitalise Spot Pad for 3-inch machines.
