I meant cleaning the paintfill I use. There's zero paint left.

    Let the paint set for a bit but not dry and use an acetone wipe quickly over it. Takes just a bit of practice.

    LBlack14 I meant cleaning the paintfill

    Take a paper towel and fold it so it has a flat surface to it.
    If just going over an unpainted surface you can use acetone rubbing lightly,
    if going over a painted surface use some alcohol on the paper towel shortly after you do the paint fill.
    The trick is to go ACROSS the lettering or sight line not with it.
    Use a paint pen with an oil base or lacquer paint that has a medium tip.
    Don't paint the face either if you decided to coat the whole head.

        sdandrea1 Paint qualifies as "whatever", seems to me you produced a demo tape of geezer arts and crafts on the Holy Grail of putters. I know, I know, painful memories of a bet😁

          LBlack14 how the heck would I get in the cavity, cuetips?

          What @darpar and @Eguller described should work in the cavity, Landon. You'll have to fold a smaller wipe to fit. If you use a paint fill marker with a small or medium tip and try to fill JUST the letters, there won't be to much over spill to clean. Let it ALMOST dry and wipe (don't press) lightly. What is left can be cleaned with a razor, or dental pick. Those tight spots take practice. The good news is, you can start over many times.

              darpar can I clear coat it and then do paint fill and clean up the paint fill without removing the clear coat?

                  LBlack14
                  I'd do the paint fill first then the clearcoat, that way you won't mess up the clearcoat.
                  If using an automotive/lacquer based clearcoat, make sure the first couple of coats are real light,
                  to seal the paint fill.
                  Otherwise the lacquer could lift/melt the paint fill unless it's a lacquer based paint too.

                      You want a good finish on a putter, try BOS. I had a Scotty done at a good price.

                      LBlack14 I'm after the paintfill won't clean very well.

                      Bead blasting is the easiest way to clean out the paint in hard to reach areas.
                      You could also scrape it out with a pointed Xacto blade,takes a little while.
                      Or just paint over the old stuff if it's not too thick and you can still define/recess the lettering.

                        How good are the girls with nail polish?? That stuff is my go to for any kind of paint fill. Every color in the world, cheap, readily available. For fine paint fill I use a toothpick and dip that in the polish, wipe excess off and put color where I want. Many light coats works way better than just dumping color into a spot. You can also get clear to go Iverson the paint fill and protect the colors better.
