Can anyone share a product name or link to the right material that I should use to separate the wooden frame from the chassis? And likewise - what is the best product to use to "glue" the bulkhead to the frame?

While I still have quite some way to go before I can remount the frame on my newly painted chassis - I have noticed that there is gum-like rubber material one the underside of the frame. Unfortunately I have no idea what this is.
