Can someone please explain to me why a car polishing machine such as this:
costs almost £100 more than this:
Both are basically the same, one polishes in a rotary fashion, the other sands in a rotary fashion. So the basics of each machine is probably very similar, just with different connections, one for sand paper and the other for a polishing pads.
Meguiars probably dont make their product, they just stick their name on it, and I'm sure the people who do make it wont be as reputable as a brand such as Bosch (which the orbital sander is made by).
