Buying more tools!

Have set up the garage more. Went to home depot and IKEA. I bought a small table on rollers and also bought a bench grinder and sanding station. I have been reading up on methods of sanding. To my surprise folks seem to be using a course grit sandpaper (60-80) but the FAA Acceptable methods indicates 150 or finer. More reading suggests that Aluminum Oxide sandpaper is acceptable. However silicon carbide abrasives are not good to use as the silicon can contaminate the aluminum. Black sandpaper contains carbon, which can accelerate corrosion. Steel wool on aluminum is not acceptable either.
