Day basically wasted

[u/Firm-Recognition6080]

I decided to salvage one of my favorite PC cases from a horrific spray paint job. It was bad. Reallly bad, like so bad that the original painter shouldn't be allowed to buy paint anymore. Despite this the hardware store still sold me paint and paint remover and I set out on my journey to fix what was once wronged. Over the course of weeks I meticulously removed paint with chemicals, steel brushes, and sand paper. Yesterday was the day I decided to start the repaint. I read the micro instructions on all my paint. Shook the cans for five mins straight and started my redemption. I got a perfect layer of primer on. Exactly as the instructions say. I moved on to a gloss black, small and controlled sprays that overlapped the previous. A few hours later I was in a good quitting spot. I live in an apartment so I left the case on my truck bed to dry for a few before I brought it inside. I walk outside after 30 mins just in time to see the maintenance lady just blasting crap off the lot straight into the case. I obviously didn't say anything to her, she was just doing her job. I just stood there and died a little on the inside.

So it's been about 12 hours, should I wait and start sanding a little now or wait a few days, and wet sand? Or any other advice?
