If you polish with a buffing machine, I recommend doing it outside. Either way, wear a mask! The Polish flecks are really hard on your lungs. Enough exposure will cause what is known as "Black Lung" or "Coal Miners Lung." Ive seen it before, lots of folks in my dads family get it. Its nasty.
I use a Grizzley buffing machine, a gift from our own Owen Perkins. I am awful with using it, but the art f polishing will come with time. Its tucked away in the main shop at the Farm for the winter, among my other power tools that normally sit in my Garage. Their place is held by a snowblower at the moment.
