I think I'm gonna give it a shot. What grit sandpaper do you think I should use?
I've done this with control panels, just rough it up real well. I don't know about contact cement, seems like i'd be hard to apply evenly.
Honestly, I think it will stick with just being roughed up. I'd guess a 150-200 grit??? If you do run into trouble try 3m sticky spray--it's a lot easier to get on evenly.
Oh, and don't use the cheap Walmart generic sticky spray.
