That's what I thought the case was, but I like to know as much as I can before getting into something.... possible something I can't handle. For now, I will live with things as is and replace the trim next year or maybe in the fall
One more question though.... why the need to keep the aluminum and the stainless separated? Your post makes it sound like there's an issue of some kind there.....or is it just for sealing against leaks
Oh, and what did you use to clean off the old silicon?
