Over the last few months I've been trying to get some respectable seasoning on this No.4 skillet that I got from Shawn R. http://www.castironcollector.com/forum/showthread.php?t=2434

I sanded the rough terrible surface down to a smooth shine, with some remaining pitting on the edges and sides. Here it is after sanding for several hours:

I thought it would be good to go, but after seasoning it several times I am having issues with the seasoning coming off in the middle of the cooking surface. During cooking and when cleaning up little areas of the seasoning are coming off, leaving it patchy an unsightly. Perhaps I made it too smooth?
My question is, can I do something to roughen up the surface to what other well used pans look like? Perhaps some kind of weak acid etch would give it the smooth even, but ever so slightly "porous" texture of a normal undamaged Griswold? And before anyone asks, I did my normal seasoning routine with THIN coats of grape seed oil, so I don't think it the infamous "flaking" effect.
