I carry out a side by side comparison test of a makita rotary polisher vs a rupes 15mm throw dual action machine. On a very badly scratched and swirled BMW 3 series bonnet, using koch chemie H9 compound and rupes course wool pads,

The results surprised me I’m sure they will also surprise you.

I’d like to do more “myth busting” style videos, what myths would you like to dispel, please comment below
