Ha ha, they are big cars, too old now, to work at speed, they are tricky around the rear fins. I just hit mine with polar seal, and a wipe of ceramic spray. I have two of the autoglym foam guns, a bit useless, i really like the look of the mjjc, I keep meaning to get hold of autoglym, to see if they can replace them. I can’t get the mesh filter out, the mechanisms are rock solid and I dont have a vice. I think my detailing is probably done for the winter now, may squeeze in a quick wash and seal at the end of October. Then its the guys at the local hand wash, they will probably charge me big car rate!! Folks keep saying the hyundai paint is very thin, so will watch for scratches, I thought the bmw paint was thin, the white showed up, stone chips.
