Started at 8:30 first job, a wee bit chilli, -4.... No issues.... Then all day didn't get above 0... Again no issues.... I use a trolley and no hot water... Simply use common sense... Keep everything off the deck, keep the water moving and keep the heater on between jobs.... Keep on truckin guys... Use common sense but after all we can't fight the elements.... So go to pub if all else fails... Upps sorry go canvassing... Lol
