Re: 69 Camaro Roof Brace issues
My roof as with many camaros seems to oil can regardless of the roof braces. A method I learned a long time ago was to take a piece of 18g sheetmetal, drill 1/4 holes on a one inch square grid.
I then skim a small layer of bondo onto the underside of the roof and press this sheetmetal into place. I place a piece of 3/4 plywood under it with a piece of corrugated cardboard between the metal and plywood. I then exert "pressure" with a few 2 x 4s propped on the floor boards. When bondo is dry no more oil canning. I then skim a coat and sand for a neat appearance.
Did this yesterday on the pass side and will do the drivers side next week when I get to it. I am doing a total of 4 panels, both sides front and rear.
