isolation coat before varnish

lol we keep Xposting.

I was referring to the black ink already on the board, not what was added in coloring. I once wiped a small board with a barely damp cloth and smeared ink into the white that had been scratched. I would have been terrified to wipe it with a cloth with that stuff on it!

oh i thought you meant did my colors smear.. the black didn't smear either when i used a soft nylon brush for my initial coat.

I used the Gac 500 and transparent airbrush extender today....sprayed it through the airbrush of course...and we have a winner. It looks like a brand new scratchboard The correct ratio is 2 parts Golden Transparent airbrush extender and 1 part Golden Gac 500. I took two pics below, the one at an angle is to show the sheen it leaves which looks like the original scratchboard surface. Photographing it was easy, no glare (I put glare on it on purpose)

Note: when you mix this stuff together it is white but dries and sprays clear.

Oh I forgot to mention I put 3 coats on it in 3 different directions

Thanks KJ...that looks like a nice finish. I think I may give that a try. Does it take long to dry?

since it goes on so thin it dries very quickly, maybe 5 minutes. gotta clean it out of the airbrush quick too
