I'm working on my first project painting motorcycle tank with a PPG DBC silver metallic. Tank and side covers are primered with epoxy. I want to two tone the tank with two different shades of same paint - one shade as it is and one tone tinted darker.

1) to mask for second shade must I use a hardner with dbc or shoot a interclear to keep tape from peeling off B/C?

2) Should I use tint or black paint to darken a special mix for second tone.

3) How long do I honestly have to CC after shooting BC without needing to sand or such?

4) Tank and side covers are primered with tan epoxy. Should I lay down white BC first or will coverage be sufficient w/o?

Thanks,

Ted
