Cellulose paint reactions?

[Nobbie]

What causes a crinkled reaction, as soon as the base coat starts to flash?

I'm nearly out of paint, and have sanded it back loads of times, cleaned it with a little alcohol, waited for it to dry, and as soon as its starts flashing it starts to crinkle. Even if it is taken back to plastic, cleaned, then a little primer, the primer crinkles when it over laps the base. If i just base coat onto plastic, the edges crinkle!

I am going to go menthol in a minute!

the solvent is biting in and making it react. take it back to the plastic and put a few light dry coats of primer on. give it a little flat and start basing it up

try giving it a couple of properly light dust coats and letting them flash off or 15 minutes, the a light ish proper coat, then top coat

Will give it a go tomorrow when it properly gone off. I've just gotta hope if i need more paint it's the exact same colour.

I'd give it a coat of bar coat before putting any more paint on. If ever I've had any reactions in the past, bar coat has stopped it re-occurring.

I usually bar coat it, then primer it, so if there are any reactions, it shows up in the primer and not the expensive top coat!

Waterbased?usually solves all evils.drying times are a major pain though!!
