Not talking about plumbers arse here. talking about the patches that are applied to the road. i dont know if they use this stuff all over the country but in the north east it used alot to fill in cracks in the road. no big deal when its cool but when it heats up its like hitting little oil slicks. has anyone ever gone down from them? they scare the crap out of me. they covered the road i take home from work with this crap i get the pucker up feeling a few time a day.
