I'd take it all apart. I believe we pulled the rod out of the sides to separate that hinge. You can chuck that rod in a drill and get it started coming out. If you are painting same color inside and out I'd spray it all at same time. Also inspect along the edges of the hood for cracks, we missed a few.
Good luck
