So I learned the hard way that metal gutter poles and water with sand in are not a good combination.... grrrr several of My poles where welded together on Friday from wet grit. I had to drive to the next clean with poles sticking in the windscreen. A half a hour job also turned into a hour so that pissed me off even more... When I had finished I sat down and thought about it and pulled out the tub of greese and greesed the connection ends. So much better now.
