need ideas on how to seal up trough under wipers

[80convertible]

After washing the vette the other day I found water on the floor board. Upon closer inspection I noticed that there are cracks in the trough under the wipers. It looks like the previous owner tried to seal them with black rtv. I would like to find a product to use to seal the entire trough. I was thinking about the black stuff used to seal a roof or maybe the black rubberized undercoating you can buy in a spray can. Any suggestions?

I used the spray undercoating and it worked for me on my 75 & 80. Also check to make sure the vent duct on the right side is closed and there is no leaf's and other junk down in the well which can block the drain holes. If the holes are blocked the water can build up on drop the water in to the floor.

Thanks for the response. I'll try the undercoating.
