My 49 four door Plymouth Deluxe has a remarkable original interior. The only real damage is on the wood grain front windows where I imagine sweat from the passengers and driver caused them to wear away and rust. I’d like to protect what’s left. Should I use regular car wax on the dash and other places where it’s still in pristine shape or is there a special product for this. The headliner and upholstery are also original and in beautiful shape. There are a few small places where moths have removed the nap. Is there something I can do to preserve the martial. Scotchguard? Any suggestions as always would be greatly appreciated. Can you still get the old terry cloth seat covers? Lanny Athens, GA
