220 3m its a finer sand paper you can take the paint as low as you want with it it works great. You should always prime over a 220 grit scratch. It is the perfect size grit. If you are sanding primer so you can apply topcoat, finish with 400grit dry on a machine (DA) or 500 wet sand for a solid color enamel. Basecoat products, particularly metallics and pearls, need to be applied over a substrate that has been wet sanded with 600 grit.

∙ 14y agoIf you are trying to get through the clear and paint to the primer, you should use a 400 grit wet sandpaper followed by 800 grit. It may take some time, but if you use a rougher grit without going back over it with increasingly smaller grits, you will see the scratches from the rougher grit through the paint job.

What kind of sandpaper do you use to remove old finish from brass fireplace?
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.

Dffrence between 180 grit sandpaper and 60 grit sandpaper?
The higher the number code printed on the back of all sandpaper the finer the grit. With a little practice you can begin to understand what grit is appropriate for any given job. For instance, I refinish hardwood floors and it requires three courses of sanding. To help quickly remove an old finish from hardwood floors I start with a very course #20 sandpaper. It is so rough that it removes a large amount of material pretty quickly. Then, when I have sanded the floor down to bare wood I "step up" to 60 grit sandpaper. Once I've gone over the entire floor with the 60 grit I "step up" again to the finer 100 grit paper. When refinishing wood floors or furniture it is necessary to use several courses of sanding to help remove the deep scratches created by the rougher grits of sandpaper. I hope this helps. John
