Thanks for the advice. I will get a proper bonding kit then. I have some kururst, a grinder with sanding pads, and some wet and dry with various grits so I plan to do it all properly, and I'm pretty confident I can remove the rust from the affected area. When I put the window back in I will give the bonding the proper time to cure also. I may as well find out how much it will cost me to get it done professionally, as if it's not to expensive it will give me piece of mind but thanks for all your help guys
