Hey people

I wanted your opinion on following point. Which Rupes polishing machine do you use for your F30 or other BMW? The LHR21 or the LHR15?

Neither. They're seriously overpriced for other than a commercial outfit that uses them every day. I use one of these for heavy and medium cut compound:

And this for polishing and sealing:

You could get away with a random orbit for compounding too but rotary is much faster. OTOH rotary is prone to swirling with polish and sealer, so you want random orbit for that.

I personally use the LHR21 mrkIII. Bought it last year. First time trying to polish the car.I can say that machine is totally not for beginners. It's a very and complex machine and not easy to handle it. Also with it's almost 3kg it's a very heavy machine
