Review on Chemical Guys BUFX_301_4 Microfiber Polishing by Mike Rubenstein

Great disc, works great on hard paint. (Like GM car paint). The difference between these and other microfiber pads is that they have foam about 1 inch thick. I think Griot is the only other brand that uses such thick foam on microfiber pads. As a result, the seal is very flexible in its contours. The only downside is that the Velcro came loose on me once after only 3 hours of use.
