John,
Have done a couple of them, not too bad of a job. You will need the seal , comes as a roll. Don't remember the thickness, there are different sizes . Will also need a primer for the surface, it brushes on. I allways picked up my supplies from an auto body supplier.
If you allready have the glass , it may be worth checking out what it would cost at a glass shop. the labor shouldn't be too bad . You,ve allready done the hard part, getting it out.
