White spray gesso here. I use white because it's easier to darken colours than to lighten them.
Hey, them's fightin' words!
I used brush on
black gesso
and it was OK. Thinned it out a little and applied in two coats.
Tried the local WalMart, as the web site said they had several cans of Krylon primer in stock. Couldn't find any in their train wreck of a paint aisle.
I may give the Duplicolor a try, or may just stick with the gesso - and try the spray as well.
