Guys
Looking at underside finishes of the 700 mile 1970 an original 71 recently for sale,
The underside of the floors are definitely a beige shade up to the seam at outer pan edge.
Then semi flat black in wheel wells.
Also engine area same black and front trunk body color

So...
The questions is What’s best product/source in USA to match or are restorers custom mixing to get the correct color?

Thanks for info
