I have recently started turning a few acrylic pens. I have been using Rustoleum gloss white spray paint to paint the tubes. I let the paint dry for 24 hours and then use two part epoxy to glue them in the blanks. What I have noticed is that after the blank is turned down to size I can see small spots of brass tube where the paint has chipped / peeled while inserting the tube into the blank. Is it possibly bad adhesion of the paint, or maybe the heat from the curing process of the epoxy? Has anyone else had this problem? Thanks.
