Painting plastic tanks, enamel paint wont dry?

Question

I painted my plastic tanks using testors enamel and it has not dried yet after 4 days? I didnt use any thinner when applying. What is the correct way? Can I get my tanks to dry or do I need to remove paint and start over

Answer 1

When I make airfix models or when I repair my old battered hornby set I always use Humbrol. I have been for the past ten years and it is a great enamel paint as it dries in just 6 hours. However if using pots of paint is not working, try using Humbrol aerosol, it is quite effective and bonds to nearly every modelling material.

Answer 2

There are TWO possible reasons for enamel paints being "tacky" after FOUR days:

1) Painting during high humidity.  The moisture in the air isn't permitting the paint to shed it's moisture and dry.

The "Cure"... buy a dehumidifier, or wait for better weather to do your painting.

2)  The miniatures are of an incompatible plastic... the enamel paints are acting as a solvent and are softening the plastic.  The reaction is constantly keeping the paint "tacky".

I'd be curious to know the manufacturer of the tanks, and your location weather-wise.

GOOD LUCK.
