I am using 1000, 1500 and then 2000 grit paper to wetsand before buffing and glazing.

How do I know when it is time to stop with the 1000 and move to 1500 and so on?



Thanks.

 

when it is flat, and the same hazynes, light scraches from the previous course, also it has no friction any more, paper is not draging, just sliding over surface.

 

All you want to do is lightly skim off the surface. Keep the paper wet and use a block whenever possible. You can buy a foam pad about the size of folded sandpaper to use when not using the block to prevent fingers marks.

 

Once it is buffed out, glazed and waxed can you really see finger marks as long as they arent dug in to the finish?

It is very uncomfortable and unnatural feeling for me to use a block. Wouldnt keeping your fingers as level as possible and light pressure be almost just as good? I am able to get a uniform haze and a surface on which the paper doesnt drag without a block.

 

It's usually if you're sanding up and down, with your finger tips facing upwards, where you'd see finger marks. Or if you're going perfectly left to right, then your knuckles make the marks. Go at 45* angles. But no, try to use a wooden block whereever possible. Only the real funny areas or teeny tiny areas should you use your fingers. (then the sandpaper over the sponge if possible).

Keep it all wet, and use some dishsoap in the water to keep it lubey-lubed.

I think 2000grit paper is kinda overkill though. The cut and buff compounds will be equivalent to 1500-2000grit usually.

 

always use a block were possible...

 

Thank you everyone. I'll post pics when I am done.

Should a circular motion be used?

 

NO, just try sanding in one direction as much as possible. Also, get yourself a little foam 3M sanding block, it'll conform to the body better than your hand will.
