I wash thinking about having it bead blasted,would this remove it?
If not it's going on eBay!!! 
Why did you buy it if you don't like that look, it would be shame to get rid after just buying it because of that?
Not sure about bead blasting it, You'd have to do some good prep and be very precise to not damage the rest of the paint, also would be a long process as the line is quite deep... Plus you may need to do a magnet test first to make sure that it is filler and not been welded.
