painting d-cell

to get the grey out…

What paint can be used directly on d-cell prior to the epoxy lam coat that won’t adversly affect the bond?

I have tried some test pieces using paints and resins with pigment and then tried to pull the glass off and the strongest bond was using a can of acrylic white auto primer but it still didn’t hide all the div colour due to the paint not getting on all the irregular surface.

thanks bluejuice… that’s just what I needed to know
