First don't have a ton of examples all cleaned and photographed of 65 Dearborn but I hope these will help
I'm doing some refinishing of the underside and engine bay of my '66 fastback. I restored the car back in 2009, and I've learned a lot since then and would like to correct a few details, especially on the underside. The car was built December 8th, 1965, at the Dearborn plant.
I'm mainly looking for:
1. The approximate color of the red oxide used underneath (I have a few photos of the original undercarriage before the car was restored, but didn't take near enough).
Sorry have no samples of red oxide from floor pans from that period and plant - only black and batch.
2. Where to break the firewall blackout and begin transitioning to red oxide underneath.
No good pictures and that area is often rusty. Basically as you stand at the front of the car and shot the firewall to the bottom end (as it bends back at an angle to meet the floor pan) the black will fade and end leaving the floor color. The transition is normally in that angled area more at the top - less at the bottom
3. Any shots of the correct overspray pattern of sound deadener in the rear wheelwells.
Not really overspray of exterior color but direct application. Consider that the painter shot the fender/quarter panel lid. the pattern was much wider than th elip so all the rest of the paint 90% approx went onto the sound deadener directly around the lip. The as he passed the gun over the opening of the wheelwell all that paint (100% traveled to the rear frame rail in that opening and the sound deadener at the back of the area
4. The amount of body color overspray that made it underneath the car when the body was painted.
Here a few shots of an earlier car - looks like allot of body color under the car from painting the rocker panel on this car (red exterior car)
Hope this helps in some way
