I do some woodturning and have used DEFT Clear Gloss Wood Finish for years. It is a readily available lacquer, and is what I have used as my head cement for about 15 years now. It can be thinned to water-thin consistency with lacquer thinner, and will penetrate through the thread to the hook. One-stop shopping kills two birds with one stone for me. The only downside to it is that the smallest container is one quart. However, at about $13.00 a quart, it sure beats the price of a one-once bottle of Dave's Flexament, etc.
