1967 Caravel.
The Jasco does work, the actual type of Jasco is the "Premium Paint and Epoxy Remover" available, as Anna Said (thank you Anna) at Home depot. I brushed it on and waited 15-20 min. The vinyl doesn't start bubbling up like paint when you strip it - but if you flick a corner up you can peel the vinyl back. It behaves, when softened by the Jasco, like rubber from a balloon, so be careful because as you are pulling it off and come to a rivet it will stretch until it pops or tears off of the rivet and it can flick some of the quite toxic Jasco onto you...so wear a mask or you will be running to the hose as little spatters start burning your skin. (not that this has ever happened to me)javascript

Because the Vinyl was bonded to the aluminum before the interior was assembled I ended up trimming along overlapping panels where I couldn't get stripper underneath. If you glop the edges of these overlaps enough the Jasco softens a little bit of the vinyl underneath the overlap - enough to let it stretch, so as you are pulling the vinyl off you can run a razor along the overlap - and as you trim the vinyl, the piece remaining under the overlap will recede back so you cant see it at all.
After the vinyl is removed there is a nice even layer of adhesive to suck up another coat of Jasco, so it is taking a while.
Good Gloves (chemical-stripper resistant) and face protection are a necessity. Stinky stuff too. Also the Jasco is amazing at melting the plastic that the 60s refrigerator vent ducts are made of, and Im sure other things I have been taking care to avoid the outer Jacket of the Romex that pops through the walls in spots so I don't know if it will melt that. Be careful.
I will update amount of Jasco used and time for the project when I finish. By the way I at first tried Savogran "Strip-ease" and it really doesn't work for this. It doesn't get "through" the vinyl.
Thanks again Anna and Greg
