Quick Help Please

im painting a 99 Silverado and i primed it up. looks nice so far but when i applied the paint the engine bay was not primed. i also fully painted that im gonna let it dry for 12 hours but im just wondering if it will ruin the model. just because i did not prime the enine bay.

No it won't ruin the model. At worst though, you may notice a slightly different coloration in the paint in the unprimed area.

ok im totally fine with that so hopefully i can detail the engine.

What are you using for paint? A lacquer product could craze the bare plastic if a good primer wasn't used.
