I had my pickup detailed a few weeks ago with Power Lock Plus. It was either pay or wait until until spring. They prepped it much better than I would have. With the cold weather my outdoor faucets are drained for the winter. So any washing will be some place I drive to. What about a touchless automatic? Self service with high pressure spray wand? Other tips to get it to last as long as possible? What can I apply on top of it myself when spring arrives?
