Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
If you want to keep it WB, maybe Matsui's Undercoat Binder-flash-top white? If I had to do a lot of these and it had to be WB I'd maybe look at HSA though. These don't DC, fwiw.
CCI has a straight WB white out that may be the ticket? In this case I would def go for a bucket of HSA, just based off what I've heard. Not sure if the hand would be soft enough though with HSA, I'm uneducated there (for the moment).
