Great Product
I have a black 2017 Corvette Grand Sport, used the Flex XC3401 & Flex 4-3/8 backing pad with Lake Country FR-HWHITE 5.5 pads & Blackfire One Step BF900. Set Flex at 5 made 8 to 12 passes, changing pads after each panel. Then followed up with 2 coats of Pinnacle Natural Brilliance Souveran (2nd coat applied 24 hours after first coat). This is the BEST results I have had over the years and I have used many different combinations of compounds, pads and tools. Will use these products and process next on a Red 08 Z06 & 02 Black Vette convertible. Highly recommend all of the above products.

works well
I have had this plate for 3 years and it has been used a lot. It still works well. At this point, if it failed, it owes me nothing.
4" plate
Excellent can run my 5-5.5" pads easily
ProsMultiple pads usage
Backing plate
Great product
Low quality, do not buy
These 2 plates developed wobble first time I used them on my Flex DA, the second time I used them one of the plates cracked, so I tossed it. The third time I used remaining plate, the center mounting hole cracked when I was polishing my car. What a junk! I contacted Autogeek, but never heard back from them.
ProsNone, completely useless and unsafe
ConsLowest quality possible!
