Should I try to Fix MB Sunburst ADDED PICS

So age marks aren't cancer? and aren't contagious to other ponies?  I thought it might be mold because the centers are darker.

The mould concept is a little bit of a pony urban legend. The marks are age marks/cancer - they are the same thing people just call them different things - its a break down in the plastic itself, the central point is where the break down  starts and the staining begins - it fades out in colour from there as the bromide moves through and in the plastic.

So no it wont spread and it cant infect other ponies
