Hello,

Bosch say that they sell three types of sand paper: one for wood, one
for paint, and one for metal. How are these different? Is one a harder
material than the other? I imagine you need a harder grit to sand
metal than wood, or is it just marketing: making you buy the same
thing three times?

Thanks.

Glass,Metal oxide... ect.

So you use a softer one for wood than you would for metal? What's to
stop you just buying the hardest one and using it for everything? I
suppose it would scratch?

What's the best type to use to remove paint? Everyone seems to sell
the "red" bosch wood paper but not the "white" paint paper. Is there
an appreciable difference?

Thanks.

All pretty useless for removing paint. You might as well clog the cheapest

cost. And clogging

Sand is cheapest, but not a very good abrasive. Al oxide is the next
cheapest, and widely used. Good for wood and paint. But paint sticks
and clogs, so a more open abrasive is used, is with more open space
between the grains.
