Coal Tar or Balck Mac which is better

[hawm]

I am wondering what the other Driveway sealers out there use and what they think is best. I use Black Mac right now and allot of my customers perfer that. I also get requests for Rubberized Coal tar to be rolled on, but I do not have this product and am looking for a supplier in my area of
Milton, or Brampton, Ontario. Can anyone help me out? :confused:ty
