He is a weird question I cannot find an answer to with searching (this is one of the few I could not find an answer for, so good posting guys!). A couple friends and I recently pulled my dads old boat out of the trees that has been out in the weather for about 8 years unused. We got the trailer back in good shape (new wiring and lights, wheel bearings guides, etc...) but one problem we are running into now is the mice had gotten into the foam float stuff that is under the riveted parts of the boat. So my question is this, how do I replace that foam (don't really know what it is called) or do we really need to? We were thinking about just shoving a can of filla foam in there and filling it back up, but we are unsure if this will work. Anyone have any ideas or tips?
