So I heard back from Bob Walker;
While he is not unequivocally stating that it will dissolve the core of the rudder in my '87 O'day, he is curious enough about the effect that he would like to dissect the rudder. This is not an endorsement of antifreeze. I will, therefore, remove it. I would love for Bob to perform his dissection for free... but I'm guessing that won't be happening.
By the way

The picture in question is this one:
This is not your picture, you did not take it (and I hope that you have not used it in your surveys) but you are presenting it as your own and using it to generate business. This is not the first time that I have pointed this out to you
, although I wasn't aware it was on your website at that time. Please remove it from your website.
Editing to add that I will remove the above when the picture goes away.
