Aboard a classic wooden sloop, the bilge has recently been painted with fresh Kirby bilge paint. However, the reddish paint has mysteriously turned purple. There must be some kind of chemical reaction occuring. Are there any ideas?

Only if wine were spilled into the paint, before it was laid on, or someone was mysteriously drinking a sailor's punch when secretly carrying on a party in the bilge, would there be wine in the bilge or in the paint. Acid...hmmm...where might the acid come from? My hunch, aside from the wonderful image of someone drinking in the bilge, is that there is some kind of chemical reaction occuring in the bilge of this 50 year old sloop. And, what might mix with a red pigmentation to morph into purple? Any chemists out there? Thanks for your thoughts, truly.

was much that he did know
He'd answer all our questions
But then he had to go"

Has your boat been hanging out with other boats of the same gender? Maybe it's time she came out of the bilge... :D

They just need to call Kirby's and talk to George.

And yes, I miss thechemist :(

Chemist, Chemist! Wherefore art thou?
Why have you forsaken us....

Isn't potassium permanganate sometimes used to clean bilges (kill parasites, such as snails) and it's got a purplish color?
