I also have cork test going on.
I used the smallest cork I could find,
drilled a hole in it, and then weighted
it down to promote saturation. There
is no indication any fuel has been
absorb after almost 7 months. Jim Moffatt
has previously stated when they started
using cork, being a living substance,
it could be subject to fungus growth.
That was the reason they coated floats.
Made sense to me but I want to prove it.
If it hasn’t sunk by 5-30-2020 it should
be clear they don’t need to be coated.
I believe the cork is treated today
to prevent the growth of fungus .
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
