I would suggest going to a local ready mix supplier and see what they carry in a silane/siloxane repellent. There are a ton of professional grade sealer manufacturers out there. Far superior in harsh climates than an acrylic sealer IMPO.......
Sunnyside Clear Waterproofer is what I used. It doesn't provide a glossy finish but seems to be better for our winter climates...gosh, I wouldn't want a glossy smooth finish on my driveway in the winter!
This stuff repels water pretty good too!
I bought it at Menards. $30.00 for 5 gallons covered 12X24 pad easily with product to spare.
