Hi, I just took off my back window hopeing to just seal it up and put it back in, but with the window removed I see it is rusted through in the upper and lower passenger side just on the lip. Are there pre-fabbed pieces that I can buy and replace with. If not what are some ways of repairing it. I pulled my soft top too and was wanting to know if there was something to put on the black dots of rust left on my roof after sanding before I cover it with water proof primer. Thanks for reading, Gary
