A 220 grit sandpaper is much rougher than the 80 grit
Second Answer By PainterJohn
No, The Correct Answer Is: just the opposite of what you stated. 220 grit sandpaper is very, very fine. In fact, it is finer than a common emery board you sometime see a women using on her fingernails. Oh, and never use 80 grit sandpaper on your fingernails, because in a very short time your fingers would be sanded down to little nubs....:-)
80 is by far more aggressive.
I have used 320 grit all-purpose sand paper. But if you find this isn't removing the brass, you can go to a 240 grit or so. Remember you are only scuffing the surface, it is just to remove the gloss so the primer has something to adhere to. I have used 320 grit all-purpose sand paper.

If the furniture is painted then you would need approx a 60-80 grit sandpaper, then gradually move to a finer paper. When paint is almost gone finish with about a 320 or 400 grit paper so it is completely smooth. If you want to repaint then you don't need to remove all the paint unless you are painting over an enamel paint with a latex. (oil based vs. water based). You can however prime it with a good primer once the wood is smoothed. Or if you remove all paint you can then stain it. before you paint/stain your wood be sure and remove all dust from the wood with a clean damp cloth. let wood dry and then proceed. good luck and wear a dust mask :-)

Yes. If you want a good finish that will last, the gelcoat must be well sanded with 240 grit paper, primed with an epoxy undercoat and topcoated in 2-pack urathane gloss.
A kiloliter (kL) is more than 240 US gallons: 1kL = about 264.2 US gallons.
Most factory aluminum rims are coated with a clear coat. To polish them you have to sand off the clear coat. You can start off with a fairly rough grit...80, 120 or so. Then start using a finer grit in steps. 240, 400, 600, 800, 1200, etc. Then follow with a good polishing compound. They'll look like chrome if you do it correctly.
