Different grits

Postby ken » March 21st, 2017, 11:35 am

I'm just starting out, and have a question about the various grits of sanding discs. The typical restoration uses 320, 600, and 1500 grits. Is there any guide as to when the 180, 500, 800 and 1200 grits would be used, or is it just trial and error?

I always use 320, 500, 800, 1200, 1500, 3000 (polishing disc). If the 320 is not cutting fast enough I drop to a 180 followed by the 320, 500, etc. In my opinion you will get way better results if you use a few more grits and keep them as close together as possible.

I do not like to give Brent likes as he is way ahead of me in collecting them, as usual he is bang on correct. If you ask the manufacturers of the discs they will tell you this is how they should be used.

Thanks Brent and screenman. I have another couple questions. I tried doing some headlights and some of the cloudiness didn't come off. I'm assuming then I should have dropped to the 180 grit and started again. This was the first time I used the kit. I also found the rotary sander slowed significantly with very little pressure. I found that frustrating. Is that part of the design? I checked the nut to make sure it wasn't loose...it was fine.
