i have an ARF that i would like to strip the covering off and paint it. I am not a big fan of covering and my question is if the plane is not yet assembled should i go ahead and assemble it first then remove the covering or remove all the covering and then assemble? As far as any open areas that are not sheeted i will have to sheet those then use fiberglass but i am not sure what size. after glassing and sanding what primer and paint do i use?
