I know some folks have just left styrofoam in there, but is there some sort of inexpensive reflective tape or wire mesh which anyone could reccomend?
Fiberglass mesh. Most hobby shops have them in small sheets, usually around the airplanes.
I just bought a roll of 3M white reflective tape that I’ll be sticking to a piece of PVC inside my N-Filter. I think it’ll look pretty neat, won’t be done in time for Halloween though so I’m working on things I can get done in time.
The tape cost about $2-3
