Everything needed to install a w/s. Butyl bead, 10 oz tube of sealer and two blocks for locating the w/s in place.
You also should get a can of paint cleaner, the liquid painters use to wipe down the paint just before painting a car to remove the dust. This will remove the sealer from the paint, believe me, you'll get it all over. Get some denatured alcohol to clean the glass. The cleaner both surfaces are, the better the stick and seal.
Tracy racy does have a good suggestion in having it professionally done, it will come with a guarantee to not leak, only if the frame is painted and no rust. They charge approx $60-75 here in VA.
Would also be a good time to replace those molding clips with new ones, use stainless screws on those nails broken off.
