I would question the expansion and shrinking rates of plastic, metal, and drip rail sealer. It seems to me if you add plastic to the equation it changes the expansion and contraction rates in every place it's thicker and thinner making the sealer more prone to crack in a shorter amount of time when compared to just metal and sealer.
