Hey if it works for you and your car projects that's all that matters.
In my life in this industry I've had a lot of people bring me, PM me, e-mail, etc asking me if they can use their wood sander to polish paint.
Usually it's because a lot of guys have some type of wood sander and they figure wood sanders are all the same. So if the Porter Cable, (a wood sander originally), can remove swirls and polish paint then the old wood sander, (fill in the name), out in their garage should be able to do the same thing.
As a result, I've had the chance to try a lot of wood sanders, that is take a place a foam buffing pad on them and then "try" to polish paint and for the most part all they do is vibrate the foam pad.
That's why the Porter Cable changed the paint polishing world, it was a wood sander that had the ability to rotate a pad and maintain pad rotation and actually remove paint or in the fluffy terms... remove swirls.
So if the Bosch wood sander works for you then that's all that's important but my experience has been the majority of orbital wood sanders don't have the power to rotate a pad and remove swirls.
