Due to lack of any other options at all we have to park partially under some trees. We've managed to get a slot away from some palms which droozled sap all over the roof, but with the summer heat in southern Spain we are picking up a lot of pollen and small seeds which stick to the surface of various mastic joints when they're hot . As a result we need to get "on top" of this so we're looking for any suggestions re access. There's a couple of car washes with gantries around, but none of them are really high enough to give us good acess all over (2.95 m roof line) . Best option to date are the tall step ladders from home (we don't have a ladder mounted on the back) but was wondering what everyone else does when on longer trips?? Any ideas / suggestions / tips, please?
