Oh ok. My previous reply had many suggestive remarks (intentionally) so I was expecting you to reply with something funny and/or sarcastic. So when all you said was "looks factory?" I wasn't sure what that meant
Spray Gloss in a can? Yes, I found it at Michaels (arts & crafts store; dunno if you have in US) I'll post a pic later. Too sleepy right now.
The bottle says it will dry in 15 mins and to 'handle" after 2 hours. However i found that on steelbooks (may be because of the metal surface?) it is still sticky after 15 mins. For 1 layer gloss, 2 hours is more than enough to completely dry. And if it's 2 layers, then 3 - 4 hours. You wont gather that much dust within couple of hours. So i never had to deal with that.
Just don't do it indoors. Will take much longer to dry. I did them in my garage with half door open.
