I know I'm jumping around a bit. Should I make different posts for each topic or should this thread be moved to another area for builds?
To keep things organized we could rename this one something like 69 Shelby #1982 Reconstruction or something like that or different threads for different areas of the car
I documented the bottom of the car today and then started sand blasting the under side of the floor. I should check out some other threads, as I am still not 100% sure of the order of the applications. Looks like black seam sealer brushed on first. But the next is where I am unsure. ................but now I wonder if that is a color that was sprayed on, or is it rust?
It cleaned up nicely so I am saying not rust. Then there is a .............semi-gloss or flat black. This looks like an undercoating as it has that run and drip appearance in some areas. ....................................
Not sure what seam sealer your describing. There are allot of different application - some applied at different times.
For clarity we try and used Sound deadener to describe what was applied at the factory and Undercoating to describe the products applied at the dealer (mark up) or after delivery
Since your car was a Shelby sound deadener would normally be applied over the undercarriage and oversprays as discussed in other threads. Normally not as thick or heavy as dealer installed under coating but one over the other makes for a fair amount of product. The sound deadener would not normally be applied all the way out to the rockers all the way along the side of the car and was normally three fairly quick passes of the wand stopping before the rear end housing (exhaust not yet in the car)
For the original floor color - try and find a somewhat protected (from the elements and rust) couple of areas - scrap off the sound deadener and clean the surface well - even a little polish/wax can help. Further towards the better as its likely coated less with any possible body color or pinch weld overspray - plus what ever paint jobs this body has seen through the years.
Given when # 1982 was likely built I would expect you will find a darker batch color as the original floor color
Also, notice the dual under floor pan muffler......... From what I can tell, they are not original. Someone seems to have changed from the factory transverse to duals early in its life.
Not unusual since the 70 up style sounded allot better and thought to flow better by many owners
