A 1974 Duster - My 2nd one, 41 years later!

Waiting on the Clear to arrive. April 7th is spray day.
I will build some sort of "make shift walk board/scaffolding"...I'm only 5" 11"...so I am challenged with the same issue you are talking about: The roof and reaching to the middle.

Maybe a safety harness and a friend to hold you back as you lean over the roof???
