I am trying to patch some holes in the roof of my truck where there was a brake light I have removed. Problem is I don't have easy access to behind the roof liner inside. Does anyone have any advice on easily floating some bondo here before I prime and paint the roof?

Cut and weld metal patches into the holes. Cutting one piece to handle all the holes might be easier.

weld them up! you can weld the small holes just like they are. the big hole will need a filler piece. cut a round piece to fit snugly in the hole tack weld a welding rod to the piece and hold it in the hole and weld. Bondo is going to shrink and show the hole and posibly crack around the larger hole.
for the Hill Billy way, you can dent the holes in some and fill with Long&Strong its a fiberglass filler with glass strands in it. regular bondo just won't work well. Jay D. they say my name is Jay

Hillbilly way?  I have found window screen, newspaper and even old shirts stuffed into holes and filler applied over the top. Of course all those areas were obviously problem areas when redoing the cars and had serious rust under the filler. 1968 Coronet R/T

another way if you can get to the back side is to cut a piece of sheet metal slightly bigger than the big hole then glue it to the back side with panel adhesive then fill the top side you'll want the metal piece tom fit tight on the inside.

That works but every one I've seen done that way telegraphs through the paint with temperature changes. JC.

^^^^^^^^^^^^^^^ Yeah, they shrink, drop, move....bottom line.... you see them. Keep with similar materials for the patch and weld....then minor surfacing.....

Only thing different that I would do is to add a cut out piece of metal to fill the hole keep Gap to a Minimum. It would be a solid No weld repair then. Dennis B.
