another Z4M roadster detail, It was a minor paint correction, goal was to remove 50+% paint defect. I also did a convertible top treatment ( not shown in video ). Owner provide the 303 Fabric convertible kit. Very easy to use...Rinse top> spray cleaner > scrub with a horse hair brush > Rinse > air dried ( can use a wet vacuum if you have one )> then apply the protectant and rub it in with a MF towel. water now just runs off the top very cool.
Client was very happy, he said it's the best gift he given himself in a long time. He was a awesome guy, just like all the Z4m owners I encounter.
anyways here's a video
