Foam for underhood use?

The thought crossed my mind, but attaching it to the back of the raiss.

I could glue it so it’s removable.

Couldn’t find a suitable rubber either though.

I was thinking about one of those big mud flaps used on 18 wheelers. As long as you stay away from the exhaust, all should be well.
