      The marks are radial Brad. I sand to 600 and I wipe with alcohol and I start with Thin CA maybe 2 coats. And I sand with the grain but I think I am simply not sanding enough with the grain. You are using a coarser grit to sand with the grain than I do. But no matter how much I apply and sand the CA will not go on smooth. I am basically doing what you do, including the polish at the end but I simply have not been successful getting the radial lines out. I will work harder with the 400 grit, maybe that is the secret.

      What is your sanding process now?  Are the marks radial (around the pen) or linear (with the grain)?
      In my case, I sand the blank through 400 before applying any CA.  I cross sand (sand with the grain) between each grit.
      I clean the blank of all dust and remain grit with a paper towel soaked in alcohol.  Not too much, just enough to wet the blank and remove all the dust and grit.
      Here's the CA portion, step by step:
      1.  apply 4 coats of CA using a fresh paper towel.
      2. do a leveling sand.  Use 400 grit wet.  Cross sand and use a paper towel to remove the grit.
      3. Do a second leveling sand with 6oo grit wet.  Cross sand and use a paper towel to remove the grit and dry the blank.
      4. apply 6 or so more coats of CA.
      5. Sand with 400 wet, then cross sand, wipe to remove the grit and residue.
      6. Sand with 600 wet, then cross sand, wipe to remove the grit and residue.
      7. If you use micromesh, sand through the grits.
      If you use sand paper, use wet/dry and sand using 800, 1000, 1500 and 2000 grit wet.
      8. use the polishing compound of your choice.  I've used car polishing compound and it works pretty well.
      I use the same sanding procedures on acrylic pens as well.  Mirror finish every time as long as I follow the procedure and keep it CLEAN!!!
      Secret is to use good sand paper that doesn't have a big grain here and there, cross sand, and clean after each sand paper grit.
      Good luck and keep us posted on your progress.

      No matter what I do I cannot get a smooth finish with CA glue. I have sanded I have tried different applicators but I always end up with some lines around the blank. Sometimes they don’t show much but sometimes they do. I try to sand them out in the final sanding stages but I just cannot seem to get them all out.
      The CA finish seems like a good hard finish, it has the ultimate shine but I need to make it smoother.
      How do you guys do it?
