Looking at the pic.... I think I see eyebrow, too...
... so if you want perfect,... it probably needs pulled out, then pounded down around the rim...(pro stuff)... (or whatever magic those auto body dudes do)...
...
... options...
a, it's character...
b, have you considered chrome?... chrome is faster, you know...

Funny thing... my buddy just bought another V-star (he buys one every other week),... that had a double (fist size) dent from a helmet drop (yeah, right)...
The bike shop we went to, recommended a body place just down the street. We stopped in to ask, and two guys there gave us a look, and a nod, over to a tank on the floor,... and said.... "Don't try compressed air";;;
The tank was,... extremely expanded (think, blunderbuss?)....
Anyway,.. the HF glue popper worked to 85% satisfaction...
Sorry it didn't cut it for you,... but worth a try...
So,....... have you considered chrome?....
You'd only be second one here with a chrome tank...
I swear, I'm 2 seconds faster... (which is a shame with all the women's chasing me down the street)....
(sorry ladies,.. can't slow down with the chrome tank,... just too much power...)...
