That's gonna need filled & smoothed up either way. If not you'll still see the lines through a sticker unless it's like a thick aluminum or metal stick on. I think it can be filled, sanded, color matched and clear blended, if you find a good painter. Problem is, it's almost just as easy on a painter to shoot the whole tank as it would be to repair it. The repair process is multiple steps and probably almost as time consuming and expensive as a full tank reshoot. (provided you had prep already done) Worse case scenario maybe just a shade off, but still may beat paying almost as much for a 'not so great repair'. Even with a paint code it could be faded just enough you wouldn't notice until you put the new paint on. It just depends on how much exposed sunlight it's seen being an '06. Sorry you gotta deal with it, but always could be worse. Give your wife a hug. Better your bike than her funeral. It's just a material thing man. You might want to change the paint job anyhow or just add another color to it, maybe like a flaming skull head on both sides or something tricky to give it originality. That would be what I'd try to do, repair the bad spots & paint another color over them expanding the whole paint theme, including the fenders . BTW...I love the fuel line & filter. Best of luck.
