I used an adhesive roll of "J" guttering that I bought at camping world. It comes in black or white, and is really heavy duty. I also put a piece over my drivers window, and over the entry door awning. It cut the water run off of the roof by about 95%. Easy to use, and easy to apply. On the windshield application, I just used the windshield moulding as a guide and adheared the J rail right on top. You don't even notice it's there.
Saw a neat fix but it would require a ladder I think.I have found the downspouts to be a pain maybe I haven't found the right one yet..tried several.
Works even with a down spout. Attach a clothes pin run a piece of fishing leader (clear plastic) down to the ground attach to a spike and eureka the drip runs down the leader to the ground..This would be a good fix when you are stationary for a long while...Happy Miles
