I had some Dupont basecoat the was slightly off so we used to to correct the top surfaces of my 1970 white stripe car. Also worked the tail panel. The last photo is the car as found out on a farm. We used a premix pack of clear that had flattener to male it mach the age of the sides. The chemical blend is about the beltline height of the door. Now peeps at work are not joking about how it looks. Also got the 1970 plates registered for the county seat adjacent to the selling dealer town in Montana. Fun stuff resurrecting this little car.
Still working to save the spoiler. Trying some FUSOR bonding products. There is a heat-activated product that sets up like plastic and seems to be working.
