I went to a home improvement store and bought a strip of exterior vinyle . It is 1"' wide and 1/4" thick. I used exterior liquid nails to glue it on the top edge of the tub. I cut it long enough to be able to slide it under the tub surround.
BTW the tub surround shold not be sealed up to ensure moisture can evaporate.
