Nothing will eliminate the wicking or drips of water running down the side of an Eriba, but the weather strip does help with an awning where it will rise vertically from the awning/gutter strip. I do not use one with a sunshade/canopy.
I've owned the genuine Eriba which is good, as is the more readily available Seals Direct. The Kampa version is a disaster. Do not buy it.
