Spray wax from the ladder and a towel folded over a push broom works.
And the spray on hose off “ceramic” stuff does a good job too. It’s like $20 a bottle but could probably do the overhead area 10x or more with it. 1 bottle does a crew cab truck about 3x.
I haven’t hand waxed anything in aboot 20 years….
