On some regular clears, it can remove a lot of clear very quick if you use too much pressure and or make too many passes. But it really cuts my work time down alot and finishes exceptionally nice.
I was recently demonsrating the cut of 106ff on the hood of someone's Ford Excursion that had been rolled, so they didn't mind any potential damage from my demo. The hood had a surface coating of 4.6 mills in the 2 X 2 area I was polishing. I polished this area with po106ff via Cyclo and Edge 2000 yellow pads. After working this 2 X 2 area for a short while with some pressure, the thickness measurement had already dropped to 4 mills and below; a whopping difference of 0.6 mills or about ~15 microns.
It's been said that much of the UV protection for the clear coat lies at the outer edge (~1/3 mill or ~8.5 microns). With this in mind, the 15 microns I quickly removed with 106ff would surely have a negative long term impact on the UV protection in this area, especially if it was left to the elements without any other protection. The surface looked immaculate after I was done, but this does raise a valid concern in my mind about the long term impact of the clear coat's UV protection when too much clear is removed.
I really like 106ff, but I always measure my surface coatings and error on the side of caution when in doubt. Not all clears will cut this fast, but it's nice to have a tool that helps me make more informed decisions towards the best interest of my customers.
