I misjudged the waterline on my boat when I applied the epoxy barrier and
bottom paint.

I will not try to fix the epoxy barrier coat coverage but I will be raising
the bottom paint line when I put the boat on the trailer (in preparation for
our vacation on Put-In-Bay) next week.

So how do you remove the scum line? I have brushed it off every time I have
been in the water and washing down the boat and outdrive, but a scum line
remains.

TIA!
