Of course keep the area COVID clean will reduce this issue when installing or removing.
3. And prudence IMO, would suggest a loose nylon? safety tether while testing. The forces to be calculated would have to as mention allow for odd wind gusts, from semis, etc, in addition, to rain reducing shear attachment, and road shock loads from roads aberrations/curbs/etc. So no matter what, you will have a big fudge factor, and the safety tether will help reduce that, IMO.
My paint is not good anymore, and I've been letting it slowly build patina for the most part. I think the safety tether is really important, and I've been considering how to do that.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
