this only happens if the paint not fully dried and another layer put on top of it, different freshness of lacquer layer contracted differently during paint curing causing cracks.
need to confirm whether the layer is to thick to dry within hours?
some also argues can spray require dip in warm water and shake at least 30s to 1 min before spray but im an ab painter so cant confirm that.
I don't know, previous batch where i spray lacquer on top of acrylic, same batch, i notice the later ones i sprayed all had cracks, and the time gap is only less than 1 minute. Never had issues with spray cans until i used this Nippon can coz i saw it in Ace Hardware, the Mr.DIY ones are too diluted so can't cover the base color. Regret, i used NOW cans witch cost rm15.xx no issue. I guess pay peanuts get banana.need to confirm whether the layer is to thick to dry within hours?

I sprayed the same way i did before than, only difference is i switch to newer can (should be same stock batch). The older can feels diluted near the bottom. I don't think paint not fully dry is the main issue since i've been doing the same thing. I did spray at good distance.
