How to Remove Rear Window Defrost Grid
 

Has anyone done this and what is the technique?? don't need a rear defrost down here in Houston and since I'm doing a glass out repaint, I thought this might be a good idea.

I researched this heavily just 2 days ago, as I just started a backdating project on my '86 and I don't want defroster lines.

Almost universally, the answer is that it is impossible to remove the lines without destroying the glass in the process. With great effort, you might be able to remove the metallic side on the interior side of the glass, but the brownish lines that you see from the exterior are there to stay.

The only option is to buy a used rear glass window without defroster lines. Since nearly all 911 production cars were delivered with defroster glass since the late 60's, I've been told the only chance is to locate a rear window from a 912.

I abandoned my quest because I found that the '73 RS was delivered with defroster glass anyway, so I already have a semi-correct window. Only problem is I also have a third brake light which, obviously, the '73 did not have. That also is something that can't be removed from the glass.

An X Girl friend used a brick on my 75 and you could not tell it ever had a defroster.

Yea, but I bet it leaked water after that. ;)

I recently "shaved" the metallic part of my defrost lines with a small razor blade. They had deteriorated to the point were it didn't work any more so i thought I would just neaten up the window a bit.

After a good cleaning the window looks pretty good. But the lines are still there. :cool:

I found a window from a 1968 coupe.

I'm bumping this up because I am on the same quest and also curious if a no defroster rear glass from a SWB will fit on a LWB like the above poster alluded to.
