Headstock shapes look interesting and like one on the left immediately above or very top right in panel showing 8 images.

With CA glue I am using it to finish off a fretless neck and very fiddly indeed plus highly toxic fumes that makes your eyes water, well at least that is how it affected me. Have run out of TO and need to do a touch up spot on one of my axes where top was accidently scorched with a soldering iron. The CA comes up clear and in a small area might be OK but would never recommend over a large area such as a guitar body as it does not dry completely flat and smooth and requires extremely delicate wet sanding to start the polishing process.

Had left things for over a week and last night thought I had it done but on the final 12,000 micro mesh sandings I noticed it was starting to go through around 2nd fret....ARRRGGGHHHH. Another touch up, then another light sand tonight plus apply a bit more to just the whole area of that 2nd fret block hoping it will dry pretty smooth and flat overnight. Looks great all polished up but damn hard to get it all looking perfect and not slightly sand through. Unfortunately those areas will not take the final car polish as too close to the bare wood.
