Easier to do in AZ, except in Monsoon season. I try to not get rained on, but up in New England the weather can be unpredictable at times. Wife and I went out in August on a nice sunny day with no rain in the forecast. Got rained on out of the blue when heading home, she was not happy.
On my 2016 Roadster, I have been replacing nuts and bolts as they corrode with stainless fasteners. It annoys me that we don't see more use of stainless on vehicles which are entirely exposed to the elements.
