I stuff a rag on top of the mount before oil and fuel filter changes. I also hold a bowl beneath the fuel filters when I break the loose and ease the filter down in the bowl when it's free.

I also filled the cavities in the mount with shore 30 urethane to slow their collapse.

I had a pair of shields but they were a paint in the rump to line up so I didn't install them.
