Well despite my best efforts I will not have time to apply the Rustoleum Epoxy driveway sealer at my DE home this year and its getting to the end of the season where its warm enough. My son-inlaw is in the business in CT (Renew Asphalt Maintenance) but too far to drive his truck. But gives me suggestions. He suggests petroleum resin driveway sealer as the best and no environmental issues like with coal tar. Also in the running is asphalt emulsion. Try to find some contractor who can apply or even has petroleum resin and I come up with none. Same for asphalt emulsion. Now some use Gilsonite but I hear that is mostly gypsies and they thin it down a lot with whatever is cheapest at the gas station vs mineral spirits. Looks like if I want it sealed this year it will be coal tar sealer. Disappointed that more people do not care about the environmental concerns with coal tar and force the contractors to get better products for the environment. I assume most people just want their driveway sealed vs investigating the product being used.
