Hey Nino, did a bit more reading today after the post above, and checked Clay's guide.
http://www.pinrepair.com/restore/index1.htm#bgIn the guide, he recommends letting the coat dry a minimum of 30 minutes. Sorry if I'm a bit of a stickler for detail, but just want to make sure I get this right, as I haven't done it before and would not want to inadvertenly muck up the glass.
Maybe waiting for it to be tacky versus completely dry will make no difference, but I'd rather ask than not ask. Was it a case where you initially followed Clay's recommendation, and found it not to be suitable (ie. better to wait just for tacky, rather than completely dry)? Thanks.
