fiberglass safe?

[firehazard]

i searched mr to see if fiberglass can be safe in a saltwater system but there wasnt alot of info. there was something about polyester resin being safe. i was wondering what brand is best/ safe? and is the fiberglass filler and polyester filler that auto body use safe? it is 100% polyester. and whats the curing time?

Has anyone used fiberglass in their system?

Companies use fiberglass for larger tanks and in the public aquaria industry. Fiberglass can definitely be safe but as far as brands and application I don't know.
