I picked up some J-B Weld for a new challenge. Does anyone have any tips from filling in the windows? I cut bits from the blister pack in the shape of the windows and taped the down so I could fill in from the inside of the shell. The rear window looks ok and I think it just needs more sanding to blend a bit better. I’m at a loss for the side windows. Next step was a door handle delete and filling the door lines. Any suggestions for making the lines go away? Should I be looking for a different product for what I’m wanting to accomplish? Any advice would be appreciated. Thanks
