Dash Painting Tips?

Ah, the brightness on this computer is really high. So probably when I corrected the brightness of the photo I made it too dark. Mine wasn't flaking so hopefully she stays good! The plastic has what looks to be little hair line cracks in it from age. It's not actually cracked all the way through. It sort of looks like a spider web is on the plastic. Is it possible to polish that off or use some sort of repair compound?

Cheers!
