POR-15 VS Herculiner, anyone?

Thank you everyone. Does anyone else have other products to use?

Neil, you've been always such a delight to deal with, thank you for the wealth of info that you've been sharing with me.
You Rock!!!! :salute:

P.S.
Where did you get those stuff? I have called the website, the lady never answers the phone.
Any distributor in the U.S. that you know of?
