The steel sunroof on the ol' Rover is very rusty. New ones are NLA. Secondhand ones very expensive - and most will be rusty too.
I have two spares. One bought recently and looked to be pretty good. But has problems.
The construction is a pressed steel frame with a single skin across it. Curved in two directions.
I've stripped the paint off my spares, to find both have pin holes in the skin - and not where they are welded to the frame as in my present one. Just a couple of holes in the middle of the skin.
What would be the best way to fix them so they have a good life? My welding place says trying to just weld the holes is impossible.
The original was bare metal'd and filled with some expensive polyester filler when the car was sprayed about 6 years ago - but started showing problems after 3 or so. So I'd like something that lasts longer than that.
At one time, lead was used for body filling. How long would such a repair last?
