Mine didn't have any significant scratches... but was really surprised so find how much mud/sand/pebbles/etc was down in the door. So scratches sure wouldn't surprise me one bit (not to mention all the direct hits they've take from branches).

 

wait you put the tint on the outside to have it get hit by branches and stuff?

 

I took mine out because I had to fix my door, not for tint; of course a branch isn't actually likely to scratch the glass, just said that as I know I've had my share of sharp branch drags and blunt whacks to the window. We don't go looking for tight trails, but seem to always run into them none the less.
