BONDO? On Buildings ?

The WW&F used it on a full scale roof which they were re-doing. it is not a antique car but nice enough. they sheathed the roof in 1/4" plywood and used the bondo to smooth the joints and fill screw holes. it was then covered with fiberglass set in polyester resin. if it works for full scale stuff why not "large" scale stuff!

That being said, it is not 100 % waterproof and will come unglued if submerged for extended periods as on a boat hull. if filling wood, the wood can swell and shrink with moisture. Wood may shrug off bondo patches which do not swell or shrink.
