Thanks for all the help, I think that this is what I have decided to go with. It seems to get pretty good reviews and claims to be;
"An industrial-grade, solvent-based, silane/siloxane sealer, Siloxa-Tek 8510 is engineered to reduce water and moisture intrusion, protect concrete from deicing salts and chloride-ion ingress, and resist staining from oil and fluids."
Anyone have any personal experience with this stuff?
Thanks again for all the feedback,
