I have been planning on sealing my drive this fall but, yesterday I was out working in the yard when a man stopped by and offered to seal my driveway for a decent price and included a 2 year warranty. Of course that price was only good for right then but, I took his card and told him I would get back to him. The price he gave me was about the same as the materials would cost me but, the stuff he uses gets sprayed down and is dry in 2 hrs where the sealer that I was going to use you need to brush it on and it takes 3 days to dry. So my question is, has anyone had their drive sealed with the spray on type and had it last or are these guys like the ones that want to paint your barn roof and use water with a little bit of paint mixed in to make it look good for a month or so ? Thanks.
