    A customer service rep recommended I use the 4500 product first as a primer of sorts to densify my driveway that has existing spalling damage and then use the Siloxa-Tek 8500 on top to prevent spalling and salt damage. The combination of both products really seemed to make a visible difference since the winter just passed and I have no new spalling!

    Lithium based densifiers are the way to go especially if you are going to be polishing the concrete and this product is no different.
