Update : the grommet was so loose that I wound a lot of waxed dental floss beneath the badge (enough so it would have a difficult time sliding down the grommet) so the badge would stay elevated when I placed a piece of wood to hold the inside of the grommet flush with the inside of the shell as I placed 1 QUICK-GRIP on the top of the badge + 1 QUICK-GRIP on the bottom of the badge and applied pressure in the hopes of flattening the badge out + thus avoiding any grommet removal. I left these overnight.
The next morning to my surprise the badge was flattened significantly out again. I didn't think it would do anything at all.
Anyway, thought some would have this issue in future. Give it a try.
