Head south on 202 toward Southwick and Westfield's driveways line the road one after another, blacktop that spends nine months in the sun and three under snow. Th Seal Coating Guys take on the winter half of that: plowing, shoveling walkways, spreading salt and sand wherever a slope or a shaded corner wants to ice. Knowing pavement makes for careful clearing — where the pitch drains, where meltwater pools, where the blade should ride. The aim every time out is a surface returned to bare, edge to edge, before anybody needs it. A night's work gets measured in clear pavement and nothing else.
