I have posted my (very time consuming but very good results ) method in one of my build threads (I think it's the Marin) - I can't see why it wouldn't work wonders on cranks to

Make sure you post up before and after pictures

So what am I best to do ?? Is it sand paper first?

 

[lewis1641]

if they are scratched or scored you'll need wet and dry before polish. use as fine a grade as you can but deep scored will need a coarse grain. go through the grades of paper then onto the polish

No! 400 or 600 P60 will cause you a serious amount of work espcially on something the size of that. P60 will remove too much material.

I'll post some pics tomoorow of something i've done using 400 only.
