Lew. I "decant" the paint out of the rattle cans and then use the decanted paint in my air brush. There are many videos on U-tube on how to decant the paint. i use the straw method and it works very well. I use all sorts of paint in my air brush such as lacquer and enamel and never have any problems. I usually use the small paint cup and refill it as needed for small jobs as it is easier to clean out then the larger bottles.

The acrylic sealers seem to work well. Johnson's Floor Wax, Vallejo clear gloss, ect. After applying gloss sealer, over spraying with Acrylic dull coat then works nicely.

Never tried in air brush but they have a small can version

Min wax in blue spray acrylic dull or gloss. I use on wood n foam to seal.

Along the lines of the clear ABS cement I have a question: Has anyone tried an alternative to Testors "Dullcote"?

I have been using this on my boats when I want to seal/waterproof things like decals or dull items like figures (which really isn't flat enough). It is getting expensive in the "rattle cans" tripling in price in the last two years (I guess this is part of what is killing scratch build modeling).

My current project (RC tank related) involves spraying in some tight spaces and an airbrush would work much better versus a spray can.

I know Testors makes a liquid/bottle version of this at a much more reasonable price but I don't want to use lacquer or enamel based paints in my airbursh.

I found some suggestions on the Fine Scale Modeler site but they did not touch on the suggestions being waterproof.

Any thoughts?
