We dive into serious body and prep work on our 1969 Pontiac GTO project. We’ve tackled the chassis and drivetrain, and now it’s time to focus on the body, especially the challenging front bumper piece known as the enduro nose. This rubber-molded piece wrapped around steel is notorious for cracks, and ours is no exception. We strip down the paint using 180 grit sandpaper, taking care not to alter the original body lines. Despite unveiling nearly 50 cracks in the rubber, we’re determined to revive this bumper to its former glory.

  1. Would the center vent do a better job of it were moved forward so as to do a better job of extracting the hot air ?directly behind the radiator? You would also need a raised surface on the leading edge to create a high pressure that would aid in the extraction process.

  2. So if these cracks appear because of the plastic flexing , does the epoxy stop the flexing or wouldn’t a new crack appear right next to the repair ? Shouldn’t the paint have some sort of flex agent added ?

  3. Never seen anyone take the time to fix one of these like this. The most common method I've seen is sanding the whole thing down, and then just glassing over the entire surface. I don't know if it's a better repair, but it probably takes 1/10th the time.
