I wasn't terribly precise. I filled a small glass jar 1/2 way with acetone 
and then stuffed in whatever scrap plastic I had around, with the result 
perhaps 2/3rds acetone, 1/3rd ABS. The texture is fairly thin - that lets 
me quickly wipe a thin layer across the build plate while it's heating up, 
with the layer being basically invisible. If the goop is too thick, it 
leaves a much thicker layer, which doesn't look great if the colors don't 
match. (And I'm not dedicate enough to keep separate jars of goop for every 
color of plastic).
