Okay so I was wondering if anyone would have any helpful advice for repainting the vita 1000 shell, I wanna get a similar Matt texture to it (I'm referring to the rear shell specifically not the touchpad piece just the shell) but equally I don't have a lot of experience and wondered if you lot had any advice

I have a PS Vita 1000 model that I haven't used for a few years, and I've been wanting to collect more for it lately. I charge it and open it up to find the left stick is acting very weirdly, sometimes drifting down and sometimes not working at all, and on the D-pad, only the right and up buttons work.

How could I fix this?
