Or perhaps a roll of foam weather seal from Home Despot, Lowe's etc. It has a self-stick backing, easy enough to put down and try. Available in several heights and widths.

Thanks for that suggestion.

I was in HD recently and picked up some. Looks like it might work if I can prevent it from coming loose. I'll report later if it works out.
