The last few pens I've made I've managed to sand through my CA finish, it's often just a small spot but nevertheless it means I've got to re-do the CA finish and sometimes even after a few coats of CA the same spot will return and I'll need to do a third application. Are there early clues to the sandthrough as I'll often discover it in the final stages of the process after already investing a fair amount of time on the pen? I should say that after putting on my CA I start sanding at no less than 600 grit but often at 800/1200 and use a light touch. I put on 6 to 10 coats of thin and 1 to 3 coats of medium adjusting based on digital caliper readings.
