I almost use the Hydro-Tech pads exclusively just because they cut more than their open-cell counterparts but also finish nicer. Another benefit of the closed-cell design is that more product stays on the face of the pad meaning a longer working time for most products. My favorite of the trio is the Tangerine polishing pad. When paired with a quality AIO such as Pinnacle XMT 360, Optimum Poli-Seal or Klasse AIO, it's an unbeatable combination. I've also had excellent success with the Tangerine pad when used with Menzerna Power Finish, Super Finish or PO85RD or any other quality medium cut polish.
Like Todd said, the Cyan cutting pad and Meguiar's M105 work beautifully together. :drool:
A couple weeks ago while prepping a vehicle for Opti-Coat application I found a couple scratches on the rear quarter panel that I could lightly feel with my finger nails. From past experiences I knew M105 and a Cyan pad would be my best bet without resorting to a wool pad or a Surbuf cutting pad. Needless to say, I grabbed my trusty PC 7424xp, a 4" Cyan pad and a bottle of M105 and went to work.
As you can see, the Cyan pad paired with M105 easily removed the scratches and provided a finish that could easily get away without the need for a second polish.
The Cyan, Tangerine and Crimson Hydro-Tech pads are a must have in my detailing arsenal because they work great and eliminate the need for six or seven different foam pad types.
Give 'em a try and be prepare to become addicted. :rockon
