I'm new to the tint thing and I got my tint last week. Just now I notice swirl scratches on both my rear windows. Looks kinda like microscratches. Like they rubbed in a circular motion across the middle of the windows. Not a big deal since I won't ever sit back there and notice.

Is this common on tints? Should I have the shop do those windows over or is there a risk it'll turn out worse? I have no idea here.
