I had a new concrete driveway put in and the contractor suggested we seal it. I went ahead with the sealer thinking the cost of it wasn't that much compared to the overall project. The sprayer that they used was not working properly and subsequently left a streaky pattern on the entire driveway. The contractor, who wasn't there at the time, apologized for the mistake and said he would roll on a new coat of sealer to correct the problem. WRONG!! Now I am left with a patchy, streaky, blotchy mess. What are my options? I attached a photo from after the first coat of sealer and some photos from after the second coat. HELP
