just wanted a few pointers on using the above as the above as it were. at the minute i'm using an open hose to sheet the water off, patting the remaining beads dry then doing sections at a time with the LT. Is this the right method? do i need to pat it dry beforehand or do i just spray LT on a panel and wipe down and buff? i read on DW of a guy using it through a power lance. . . sounds wasteful to me and not the way i thought it should be applied.
