forgot to mention yes the LSS and solvent top coat products will amber and over time it will more so. With Dn as top coat you should be fine. With the LSS you could dip all day, just don't know what it would do to the foil. The waterbourne Lacquers go on white and cure crystal clear and have added uv resistance and durabillity, but harder to sand and apply. Will your DN not even out everything in the end. I'm using LSS-Creatix- Duplicolor Acrilyc Enaml Gloss In spray bomb and is working for me, but I'm only doing a few at a time.
