Belkins456 - It's hard to say all what might have worked. I don't know if it was a combination - but I know this was the 3rd winter before this thing held any water.

I think for what you are trying to do - as I understand the DB100 - that's what it is supposed to do. You should be able to just spray it on - period.

I hope you give it a whirl - it can'r hurt! Let us know.
