I know this thread is 9 years old, but I figured I would ask the question here first before starting a new thread...
I'm at the stage of removing the windows, but I cannot get the bottom 2 screws out of almost every window. I wanted to re-use the black metal piece, so I don't really want to go at with a tool that would damage the metal. I don't have any apparent rust, so it isn't like I'm battling rusted or stripped screws. And I am using a DeWalt power screw driver/drill. I also tried putting WD40 on the screws to see if that would loosen them.
Does anyone have any suggestions?
The upper screws were also very tight, but with enough pressure on the power screwdriver, those came out.
Thanks!
