Larry,
CA seems to scare some people, but it is actually an easy and very durable finish to use. I use thin CA, turn the lathe to its slowest speed, roll a small piece of paper towel and apply the glue to the towel. Then hold the towel to the wood and keep it moving down the call. Just keep reapplying till you achieve the desired finish. Speed the lathe back up kind of fast, lightly sand with 400gr, then 800gr. Stop lathe and orbital sand by hand with the 800. Turn lathe back on and polish with EEE or some fine polish and then you are done!!!! I can finish a trumpet in about 5 minutes
