GRP, boatyard, lay-up workers are all fans of chewing Skoal, Copenhagen, etc.
They can't carry their usual spit cup around with them when in the mold doing the
lay-up work. So, they spit the juices into the mold and lay-up as they work. These
juices are what one sees as a green substance coming out of some GRP hulls.

I hope this helps.

Many of the fiberglass/plastic boats I've seen here in the shipyard
have blisters that when you pop them like a zit are full of green
juice.

Just what is that green juice you plastic boat people deal with?
