Continually impressed with Rupes Zephir and Keramik polishes, and their associated microfiber and foam pads.
I like how they spread out over the work area, and how they stay "filmy" during the buffing process. When I use Zephir as directed with either pad, I don't get anywhere near the dust that I did last year when I over primed, and washer modded the tool. I'm also impressed with the cut/finish ratio Zephir had with either pad.
The Keramik does a great job cleaning up lightly messed up paint. The microfiber option only extends it's versatility. I've been "one step polishing" a lot with Keramik and the yellow microfiber pads, and the results are exactly what I'm looking for. When I want maximum gloss, I use the foam.
Both polishes wipe away very easily, which is nice. I do have some Keramik that I got second hand, and doesn't have the thick, creamy consistency as the new product I got here from AG. Sometime that will be difficult to remove. Nothing serious, but I do have to pay attention during removal. It was probably left in extreme temperatures or something. The new, fresh product is effortless.
The tools I use the products with are the Duetto, and Mini. What can I say? They're my perfect fit. Not only do they make the job easier, they're also enjoyable to use. Simple, efficient, compact, and refined.
In general, I'm extremely happy with the Rupes system! Very glad to have it!
