I'm about to seal my driveway for the first time since having it laid about 2 years ago. The only half way decent product I can find is Black Jack 5-gallon Drive Kote 500 E-Z Stir and Filler for $18. Is this product any good or is there any place I could find better that you pros use. The estimates I got were for around $500 which I can not afford right now. It has to be done so I estimate I can do it for around $170 for 8 buckets and a squeegee with a half day of labor. I have everything else needed.
