Strange Inconsistent Vertical Scars/Artifacts on Prints

[cwmain]

These test prints on my Droplit have dotted scars or vertical lines all around them . I'm wondering the cause of this so I can fix this. Batman is about 40mm tall and the cube is 14mm.
Below are pics of the prints and my CW settings. I'm using a petri dish with QSIL 216 as a coating http://www.amazon.com/gp/product/B005RY ... UTF8&psc=1

Has anybody seen this before? Or know how to fix it? Dusty mirror, damaged vat? Bad coat material? Too much exposure? I'm very close to having good prints Thanks!!

easy solution - it's definitely worn out silicone.
the lines you see - is that small area on your vat coating, which has accidentally worn out / damaged / scratched, etc - definitely due to previous prints,
stuck prints - anything mechanical which could have caused damage.

take care
