Airbrush Microgloss Problems

The instructions from the manufacturer are pretty clear - thin the solution by 10 - 15% with distilled water and airbrush at 25 PSI. That should prevent any problems with the Vallejo lifting off in the future.

Thanks for the advice. I don't see this listed anywhere on the bottle. Can I ask where you found those instructions? Anyways I think I was able to repair the paint job (it'll never be quite the same). I grabbed a bottle of Liquatex High Gloss Laquor and airbrush medium. So far those seem to be working really well.

My 2 cents....

Vallejo doesn't play well with alcohol, period. I just went to the bench and hit a test piece of 2 week cured Vallejo with a 71% ISO dampened Q-tip. Vallejo lifted off with only minor rubbing.

Alcohol + 'wet' Vallejo = globby mess, BTW.

What is Microgloss, BTW?

I have never encountered an acrylic paint which is water soluble after it has cured. You could leave it immersed in water for years and it wouldn't wash off.

If your gloss coat is dissolving the underlying paint, regardless of thinning medium, I would think that you are applying it too heavily. Apply in mist coats, allowing each to dry before recoating.

Try tests with a lower percentage of alcohol.  91% is pretty wicked stuff.  Water may not dissolve properly cured acrylic that easily.  I don't think you can immerse an acrylic-painted model in a tank of water for a long time, but something that goes on in a thin coating and evaporates fast may not harm it that much.
