Bucko,
Thanks for the suggestions, I have powder water but it is a PITA to use it does a good job though just takes forever to do a firetiger paint job gotta dry and cure for each color. Tried the Powder airbrush but it wastes too much powder or my dust collector is too effective. I do not have a reclaim system but I do have a sensitive wife and she gets upset at that funny colored dust and when shes upset, I am miserable.
Clear coating them afterwards with epoxy has IMO a negative impact on action and airbrush even with acrylic clear coat does not hold up.
Something about rocks and toothy fish does not agree with acrylic finishes
