I've read that Scream01 on deviantART used some sort of transparent red spray paint on her Soundwave Costume's visor, but I don't know what it's called. Anyone have any suggestions/know what it's called?

Something like this?

Yes, that's what it is! Thanks, perfect for my Jazz costume. XDD

be careful with aany spray paints if it goes on blotchy in that situation there really is no saving it. I would put the can in a bucket of warm water for 15 minutes before I use it, that helps to make it spray more evenly to give a finer finish

You can get that transparent testor's at Hobby Lobby or any model specialty store. I don't remember seeing it at the Micheal's around here, but maybe yours is more awesome than mine and has it. It is transparent though so you may want to slightly mist some silver over the visor to obscure your eyes. The more silver you use though, the more obscured your vision will be though.

Thats a good tip and I never would have thought about that. Thanks!

So, after wearing the Arcee mask for two days I can say for sure that even though the blue is transparent it definitely blurrs things. Don't try to read things, I tried that at the anime dating game and failed, had to slide up my mask.
