Empty JBL AS1025 install redone?

[djlivex]

I just bought a pair of empty JBL AS1025 install subs. They are empty it has the connector panel, wires and f/g exterior white paint. Its in very nice condition, I bought it because I figure why build another project when these pair were only $150 in Baltic Birch. I have a total of 8 JBL 2226H, 4 have been reconed professionally last year, have not been mounted 1 slightly used 2226H, 2 needs reconing, and 1 2226HPL already recently reconed. So I have not yet finished my JBL subs from another thread. I will need another 2 weeks before they get done.

Anyway, my question to you it has a white stiff white cloth on a ply frame bolted to the front mounting 1" square ply. Now I do not like this white cloth and would like to replace it with steel perforated 3/16" hole grilles from Reliable Hardware. Also the interior of the cab has fiberglass wading. My question is breathing the fibers in my house or at DJ venues can possibly cause lung cancer long term? Should I replace them with pillow Poly Fill from WalMart? Would this be safer than fiberglass (Yellow) from the JBL factory?

Also since the exterior has fiberglass for exterior installs, I was planning on sand it slightly, then paint it with Duratex custom Battleship gray like my other 2 JBL sub project or another type of epoxy paint from Home Depot mix?

Thanks guys for the guidance, please let me know your thoughts.😉
