We had a week and a half to black out all existing line striping, crack fill 20,000 linear ft of cracks, apply 2 coats of sealer and do a complete lay out of the new parking set up while the plant was on shut down.  Although weather did not comply with us raining 4 days we completed the project on time seal coating 1.5 million sq. ft.  The line striping lay out plan that the client provided was not correct from the engineer and we had to set up the parking lot using surveyors points.  Hardest job to date.
