Reply To: Rear screen seal

David,

Rear window does not have a rubber seal and the design of the aperture does not lend itself to retro-fitting one.  The glass is held in place against the bodywork by a plywood frame and the seal is simply(?) achieved with a layer of mastic between the glass and the bodywork.

Usual cause of leaks is a split in the original mastic which is prone to cracking when it age-hardens.  The water that gets in then not only stains the head linning but, if not stopped, can cause the ply frame to delaminate allowing the window to leak even more.

In the past I have used a black silicone-based product which air cures but remains flexible and therfore does not become brittle with time.

And the main seal on front screen should be bottom centre.
