I dunno why, but ever since I bought my car, I found the calm grey/black interior was always being interrupted by the bright yellow and red airbag warning stickers on the visors outta the corner of my eye.
I've been casually looking since, but I finally found a can of actual *GREY* vinyl paint! Last one sitting on the shelf at the newest crappy tire of all places. I usually only ever see a large quantity of black and a few white ones.
I sprayed them outside while it was a bit chilly, and it was starting to pull on the vinyl and make it wavey. I brought it inside to dry and it turned out fine. I also sliced off that clear plastic strap on the driver's one, that's meant to hold a map I guess, that I never have nor will ever use.
