Which Sand Paper Grit to use?

kenchan

well, you can wrap the sand paper over a block of wood or something to get a similar effect of a sanding block. i just happen to have sanding blocks in my pdr arsenal.

yah, definitely smooth it down completely before vinyl. you'd be amazed how much the bump will show through on a non textured glossy vinyl..!

Sanding blocks for paintless dent repair??

I think he meant for the smoothing out.
What I did was, I let the touchup paint seep into the scratch, then waited until it dried and added more layers until it formed somewhat of a mini-mountain of a line where the somewhat deep scratch was. Now I just need to sandpaper a smooth it down.

Oh I know, but in PDR no paint work is done at all (hence paintless )

PDR isn't always possible, and you don't always know this before you get started. So in cases where you can't just massage the dent out, you will need some form of paint correction, usually minor. Hence, the PDR arsenal does include paint repair tools.

See if you can find some Langka around. A lot easier than trying to sand a tiny little scratch. Although it's supposed to be used right after touch up, it will work a week or two later.

Yep, when you have multiple impact points or even multiple minor high spots that don't hide well in the orange peel, we use a sanding block to smooth out the irregularity on the surface to blend. This tricks the eyes thinking the surface is flat per the flat reflection in the paint.
