My 72 Fury is garage kept, 100,000mi. The white top is in good condition. I just wash it with the rest of car and wipe down. Looks great but again garage kept
I have a shop in a poll building. Cement floor and insulated and heated. I run a dehumidifier in the summer. I keep the doors and windows closed most of the time to keep it cooler so the moisture likes to collect inside. I just empty it daily on the flowers outside
A friend of mine ordered some for his Challenger , had an extra set left over, used them on my Satellite. I'll find out where he got them and PM you in a few days.
