I'm painting the plastic parts of my car interior, but the paint keeps doing this.
Does anyone know why this happens or how it can be prevented?
I applied 2 coats of plastic primer first, so that can't be it. Is it just shitty plastic?

If you proprly primed the surface, it's either some specialty paint (not compatible with primer), large amounts of moisture, poor cleaning or old paint.

Those are "fish eyes" caused by impurities on the base. If it's automotive interior then it needs a major cleaning before any spraying due to numerous chemicals containing silicone, Armor-All to be specific. A good wax and grease remover and some elbow grease will get it off. DX-330 from PPG is my go to for cleaning interior panels. Remember to clean BEFORE you sand or else you risk embedding impurities into the substrate and you'll never get them out.

Ok, thanks. I guess I didn't clean or sand the material good enough beforehand. This rubberish stuff tends to build up on VW MK4 interior plastic and maybe I didn't get it all off.
Is there any way to fill most of these holes up?
Do I just try to apply more layers of paint until most them are filled or would this be futile?

as mentioned they are fish eyes.

Next time google this shit.

find an autobody supply store in your area, they will have what you need as far as adhesion promoters and everything you need to do a professional job, Vatozone and peepboys and the likes have stuff for rookies that don't know the difference


and why are you painting this shit red?

The autosupply store is where I got my primer and paint.
And because a black and red interior looks dope as fuck
