Someone could probably pull it out with a stud gun. That paint will chip sooner or later, so you'll need to repaint. If the rest of the body panels were painted with the tank, you'll need to have the color matched. If it was done with a spray-can, that's no biggie as long as you can find out what was used on the tank in the first place.
If it was done with professional paints, any good paint shop can mix up some matching paint for you, but you'll need a paint gun and compressed air to lay it down.
Are you looking to do the tank yourself?
If you're in no hurry, John68 has said that he'll do "mail-order" paint jobs, so if you're looking to have it filled, color-matched, and sent back in clean condition send him a private message asking for a quote. I'm sure his price would be comfortably inside a couple of hundred dollars (I might be fuzzy, but I think his quoted price for doing tins w/o bodywork from the whole bike was just a few hundred), and I've seen his quality. It's very nice.
I guess the most important questions are:
- Are you looking to paint the tank yourself?
- How soon do you need the tank back if you want it done professionally?
