Reuse windshield weatherstrip?

Ok first it's called a gasket. Yes they can be reused and they fit better than most repops but....
cleaning one is a time consuming chore. We lay them on a table and work with charcoal lighter fluid, plastic ( pic-nic ) knives and rags. You should find some grayish window glazing putty in the glass channel and butyl sealant in the body channel.
A friend of mine thought he would take a shortcut. He submerced his Chevy pickup window gasket in a 5 gal. bucket with kerosene for several days. That gasket grew so big it would fit a school bus. LOL
