While working on my dingy Sunday, I came upon a particularly difficult substance to remove. I was coating a piece of ply in epoxy and mounting it to the transom for the motor, and there was a 'goo' that acetone would not remove.

I went to MEK, that I found in a rusty can in the flam locker, and it worked.

I remember years ago, that I had decided MEK was a substance I would no longer use, (something about being absorbed through the skin and there being no means for the body to excrete it) so I went online this morning to refresh my memory.

Came upon an unrelated piece of information about MEKP

Methyl Ethyl Ketone Peroxide that is used to cure polyester.

Apparently, if it is exposed to acetone, the results can be drastic. Kinda scary considering the two chemicals are regularly used, and stored together.



Note to self. Don't store poly catalyst and acetone together.


Here is where I found this, fwiw

Any thoughts Ebb?....
