Reply To: coating for cork float

[David Stanton]

In addition to clear model airplane dope, I’ve heard of people using superglue for a coating, but haven’t tried it myself.

On the subject of corks, there was a message string here awhile back where it was found that all cork is not the same. There is open-cell cork that will soak up gas if not coated, and closed-cell cork that will not. I had a wine bottle cork that had been removed from the bottle with a slick cork remover that did not make a hole in it. I put it, uncoated, in a Johnson gas tank to run the gauge. In a month it had sunk to the bottom.
