resurfacing conc w/asphalt sealer ? ? ? whoever said this was a good idea ? ? ? the guy at the apron store ? ? ? its the wrong material - if you want to ' seal ' conc, there're sealers SPECIFICALLY FOR conc,,, if its aesthetics, there're polymer-modified overlays that can be tinted black.
i suspect you just put stuff in cracks - crack sealing & crk filling are different,,, never heard of ' Presto Patch ' but, w/that name, i can guess why the uninitiated'd choose it,,, the correct way to do what you want's much more complicated however even a 5th grader can understand & accomplish it.
wait til spring & see what happens,,, you're aware, of course, that once conc's sealed as you plan, you'll never be able to remove it however it will wear off by itself as it will - especially under wheel paths,,, nor will the 'black' of the conc match the color of the asphalt sealer.
