With a little research or a call to Reynolds you can pick one of these Urethanes that will
match the hardness of the rubber you are replacing. The trial unit is 3lbs. and runs a
little over $30 plus shipping.
This is a 2.75lb. unit of Flexible foam I’m going to experiment with this winter for making
weather strip seals for the front sheet metal, but it’s typical of the trial units:

un-opened, once you open them you can cut that down to a few months. So it’s
best to plan your project out so you use up all of your material, even if it’s pouring
some washers or small sheets with the left overs. Plan Ahead!
Here's a mistake I made several years ago in purchasing the
material for a future project, which ended up being
10 years in the future:
