I have a Daiwa BG and was respooling and when I took the line off the “braid ready” rubber band type thing that is on the spool fell off. Will this have any negative impact on the reel without this on there?

Only if you’re trying to tie braid directly onto the spool. Braid will  slip without monofilament backing or being “taped” down.

If you have any double sided tape, wrap a short piece around the spool and you’re off to the races. Same effect. 

I find a lot of uses for PE/acrylic mylar film tape.  

One of the best is seizing an arbor knot in braid to spool.  

the tape is extremely tough, only comes off when you want it off, and doesn't leave a glue residue.  

  

 

The tape is so tough, I use it for seizing knots in kayak trolley line, and the tape lasts as long as the double-braid sailcord.

Ah! Nice! I need to give this a try.
