Thanks, will the acid not damage the tar, or at the least stain it as well? Looking at some other forums since..looks like acid has been recommended for a reverse situation of tar on concrete - to get the tar off. Maybe sealing with black sealant may be safest option to get all uniform again..as at the moment I got grey patches on black? Tx
