So after my haul from Waxstock and pondering over the weekend (and bad influence from @X3man and @jassyo06 ) I'm currently looking in to buying a Das 6 pro plus, and tackling the S5 myself. Not sure if Ibis White will benefit from the treatment or not. Only bit I'm not sure on before ordering, is a 5" plate on the Das 6, surely is too big for areas such as the side skirts on the S5 so not sure how to tackle this.
LOL - Once you start using, and see the results, you will be very very happy! I also have a mini da, but tbh, for my initial correction and coating of X3, the "normal" da did the job, even on the smaller bits. Gets a bit tricky round mirrors, but some polishers offer extensions etc. Worth a chat to someone like Imran from i2d
