while it's true that you can get polishers like this for less money, and likely also true that you can work magic with them, I have to say that I am consistently pleased with Griot's. When I got this latest toy, I thought it looked a bit too much like an "in-house" creation and not so much what I would expect from a "professional tool" as it's advertised. That feeling lasted about 15 minutes, the time it took to unpackage it and start my play time. I have this, and the 3" inch and I've done more amazing work on two cars in the last week than I think I've done in years.Pros:Works as advertised, EASY to control!!! EASY to maintain, change pads, etc. OH, and definitely use their polish, it washes out with water and no mess. I had black rubber mess all over my pads in addition to the polish and it came out with running water.Balanced and naturalComes with instructions that really deliver what they promise to. So many times you buy stuff that comes with a "perfect world" scenario in the instructions that you just can't seem to replicate, well, not Griot's. What they did on the videos is exactly what I did in real life.Complete so far: (using #3 polish, yellow pads, orange pads, and rubber restore1999 Camaro Z28 HEAVY hood and door sill oxidation and clear coat breakdown- Solved with like new appearanceSame car, fully oxidized headlights, full restored to the point that I don't need to buy new ones.....clear and clean.Same car, window and door exterior rubber welt/weather stripping, oxidized, partially pasty white and appearance of deteoration: fully restored with light sheen and factory appearanceSame car, window quarter panel: discolored and faded: fully restored and shiny.
