First off let me say I live in Florida, the humidity capital of the world. All of my 68's interior had been stored in New York for many, many years and my car has been here in Florida being worked on. A couple of years ago, I brought all of the interior to Florida. For a lack of a better place to store it, just put it back inside of the car.
I sent my car to the paint shop a couple of months ago and had to empty it. My space inside my house is very limited so I put the seats in what we call a Florida room. It is an enclosed room attached to the house. It has plenty of windows and ventilation but no air conditioning. And it gets plenty hot in the summer. I had the seats wrapped on old sheets to protect them.
I pulled the sheets off of my back seat tonight just to check it's condtion and I got a big suprise. The top of the rear seat back was covered in mold. Really bad! I cleaned it off with a wet rag and then some upholstery cleaner........but then I got a bigger surprise..............
The mold had left depressions, like pock marks or craters, in the surface of the vinyl. Like sheet metal would look like if it got pelted with steel shot.
For being 45 years old, these seats were almost in pristine condition. When I saw those depressions, I almost wanted to cry.
I haven't checked everything yet but I think the damage is limited to just this seat back only.
SO MY QUESTION IS......has this ever happend to anyone and were you able to fix it. I was thinking of putting it in the sun tomorrow to see if it might smooth it out.....I don't know if that's a good idea or not......or maybe I should apply something to it that would help.
ps.....even if I have to put my bed outside to make space, I am putting all my interior inside in the air conditioning till it goes back in the car.
