I note that many builders have added black pigment (dye) to the first layer of epoxy resin/filler laid around their windshield. This is obviously to achieve a more aesthetic finish when the finished product is viewed from inside the cabin.
However I would suggest that all black pigments are based on carbon black...and I have been advised that interfacing carbon and aluminium is a no-no because it promotes rapid corrosion. Of course if corrosion were to develop at the interface between the aluminium upper skin and the pigmented epoxy it could result in a loss of the windscreen.
Does anybody have any LONG TERM experience with using black pigment in the windshield fibreglass....any other comments.
