I changed things in the last year. I removed the air dam and skirts made from lawn edging and gutters. I replaced them with garage door seals cut to fit. The work just as well but look much better and are more flexible but still stiff enough. I used automotive emblem adhesive to attach it and so far it's working for several months and ALL kinds of weather with no problems. I tried using double stick tape but it didn't work very well. The garage door seals are the same thing as the rubber air dams and skirts on E-Bay but without the double stick tape already applied. Chumly
