Youdathunk a jizz crust would have formed already

I don't think anything will hold up to the use, sweat, grease etc that a dpad gets.
I had an aftermarket resin printed set of buttons for a miyoo mini from a prominent etsy seller, and less than 1 year in (approx 25hrs gameplay), whichever coating they used became gummy and I had to scrape it off. I would imagine with the volume that guy pushes he is better versed on button coatings than anyone. And it still failed.
You could try the hardest most chemical resistant 2k clearcoat and just mask around the dpad, spray, and then give it a ridiculous amount of time to fully cure (maybe 2 weeks?), with an expectation that even that likely won't last forever.

I didn't say you had to order it from Amazon, poorfaggot supreme. I think you're just too scared to open it.

Watch a teardown video and tell me that you'd want to do all that to replace a button

That's nothing. It just takes time and patience. If it's so valuable to you then it shouldn't be a big deal. You can clean the carbon pads and PCB contacts while you're in there.

clear nail polish will work

You have to take it apart anyway to fix it without gluing the button in place, fucking man up or ignore it.

if you're too scared to take it apart why not order or make some custom stickers for it? You can replace the sticker when it gets worn out

Cut out a sticker made of grip tape

I did it for my SP because I had a defective one from the really brittle batch of plastics
It's not that bad, though I will say the hinge of the SP shot out like a fucking rocket and it took me 20 minutes to find it
