Gail - thanks for replying. I think I'll stay away from the sprays as I have to use them outside (screened-in porch) and it's way too humid down here for things to dry at a decent rate.
'blue - thanks for your comments. That makes me feel relieved that I'll mostly likely be happy with the varnish I purchased to paint on (instead of spray). I'm definitely going to do it inside (i.e. AC, ahhhh) because of the humidity down here (yes, hi y'all
). I paint thinly, so I'm pretty confident the paintings will be dry enough. Still, it's good to know that the varnish won't prevent the paint from drying more if it needs to. And it's good to know I can paint over it - I think... Ha, ha if you know what I mean. (Sometimes (ok MOST times) it's hard to say "OK - it's done!")
