I don't know if this will help, but with my Pinto came a tube, from Ford Parts, that has extra 3M Vinyl. Not enough for a car, but if I ever got hit on one panel, I'd have enough to repair it with.
It was stamped with all the part numbers and original order sheet (and aplication instructions), all referring to the Pinto Squire.
I'll pull it out of the garage and post all the part numbers and contact info I can find..... however it was dated in the mid- 90's. So you prob. won't be able to get it through Ford, but maybe through a 3M cross-reference?
