I bought some cheap replacement styluses for a gadget with a plastic pressure-sensitive screen (a Wii U gamepad). Being cheap, the seams between the styluses' plastic halves are not well sanded, and the tips have varying degrees of scratchy protrusions that might damage the gadget's screen.

Said stylus.

What's the best way for me to smooth them down myself? Just a certain kind and grit(s) of sandpaper? If so, what kind/grit? If not, what else? I am extremely beginner level with this sort of thing, so you probably shouldn't assume I know even basic facts.

  • Wow, I didn't even stop to consider that. All I saw was, How do I remove the parting line from something made out of plastic?. I don't think it'd have been closed if it asked about removing them from the handle of your hammer... Replace stylus with tool and I'd say we're a go. I've applied my advice below to lots of my tools. If you use sand paper, you'll wish you didn't. – Mazura Jan 10 '16 at 17:10

Plastic doesn't sand well. I'd CAREFULLY use an exacto knife on the parting line. Then polish it mechanically. Don't use turtle wax or anything like that; just rub it aggressively on some cloth. I.e., your jeans.

For me, my lighter makes a good backstop while in my fifth pocket, you might want to lay the cloth on a hard surface or you probably won't be doing it aggressively enough to do anything.

    Also, just to add on to this.. If you are worried about ruining an expensive piece of tech because of a cheap item, I'd suggest just getting a higher quality stylus; they don't really ever cost much. – TFK Jan 9 '16 at 4:08
  • Agreed, sutures (stitches) aren't cheap either. – Mazura Jan 9 '16 at 4:15
