I had a Genuine stone protector attached about 3 weeks after purchasing my GLX-R by a Mistu dealer. I removed the stone protector after two years and 90,000K's and noticed that it had warn the paint away from the bonnet down to bare metal where the attachment clips were.
I contacted Mitsubishi and they didnt want anything to do with it when trying to claim it with warrenty.
NOT HAPPY!! Be careful if you have one attached as it is now going to cost me alot to get my bonnet re-spayed....Thanks Mitsubishi!!!
