Painting plastic model train but paint is still sticky after 3 days?
I have repainted a plastic model O gauge train using a can of automotive spray paint. The surface is still sticky after three days. Why is this ? Will it eventually dry after a week or so ?

How heavy did you spray each coat? How long did you let each coat dry between coats? How humid is it out? These factors can keep paint from drying quickly. Put it in a cool, dry place for a couple of days and see if that does the trick.
Some automotive paints were not designed for plastic and some required a hardener in them. Yes the paint will eventually dry (give it plenty of time) GARY
Some automotive paints have a solvent that is incompatible with plastics like styrene or ABS. The solvent hasn’t cured yet. As someone mentioned, put in a cool-dry place with plenty of ventilation and you’ll be fine.
I often have models stacked up for MONTHS during the winter (our humid season) while I wait for the humidity to drop.
