Default Getting to the bottom of it... (Ablative question)

Hi, Jere, and group,

As many of you know, we're close to splashing our 2-year refit. It was
newly ablative bottom painted when we bought it.

A local asserts that the bottom paint is dead, and it will have to be
redone.


Ablative paint doesn't "die".


That's what I thought. My presumption had been that one scuffed it up
to get off the sloughed stuff and reactivate the stuff, as well as
provide a tooth for the new stuff to adhere to. You wouldn't believe
the amount of contradicting assertions we've gotten in the last few
days. That's because...


BUT, since you have the boat out of the water, why not splash on a
couple more coats? the boat's already dry.... Make it a different color
if you don't have a "reveal" coat under what's there now. Put extra
coats at the waterline, leading edges, and the whole rudder.



The plot thickens (like epoxy in hot weather)...

Our boat is covered in poorly repaired blisters. I'll try to keep it
to the short story that it was sold to us as blister-free, but on
survey (2.3 years ago, during the purchase) it was obvious that there
were many blisters. Our current gallery of August06 in the repair and
refit sectoin of our main gallery has the blister pix, if you have a
curiosity of that.

These blisters are largely dry - only a few smelled when chipped off -
so they aren't really an issue. However, lots of grinding has taken
place already, and we're going back with epoxy over all the grinds, and
fiberglass where deep enough. We've had directly contradicting
assertions from supposedly knowledgeable people as to whether that's
the right stuf to use, but that's what we're going to do absent some
authoritatively documented reason why not is presented.

Some time in the past, this boat was peeled and presumed epoxy barrier
coated. The grinds above have confirmed the barrier coat, but prior
repairs of blisters were done solely for cosmetic purposes - many of
the ground areas show prior blue marker lines - just like all the rest
of the 3+ weeks it was in the yard prior to sale: all cosmetic, no
substance....

So, we'll patch it all up, addressing only the worst of the blisters,
putting more of the same color paint on the repairs, give a scuff sand
to the entirety, and paint the snot out of it in a different color.

In our grinds, it was apparent that there was an underlying red paint
over the epoxy layer, and then the blue we are wearing and grinding
now. We'll probably go back with another red, unless we can find
something else interesting for contrast color.

The names are now also on the bow, along with the mini logos, plus the
larger logos on the stern, and the hailing port on the transom. The
Flying Pig is aloft and gaining altitude :{))

FWIW, we've started a yahoogroup for our loglist, some of you having
previously requested being notified of such. You can find it at
http://groups.yahoo.com/group/TheFlyingPigLog/, and join there, drop me
a line for an invitation, or just click the link below to send a
message to the group. It's currently open - that is, anyone may join.
It's also unmoderated, meaning anyone can post. However, it's not
intended as a discussion list, so that may change if traffic goes
aground too often :{))

Skip, back to hard piping the stern head, and Lydia, back to epoxying

"And then again, when you sit at the helm of your little ship on a
clear
night, and gaze at the countless stars overhead, and realize that you
are
quite alone on a great, wide sea, it is apt to occur to you that in the
general scheme of things you are merely an insignificant speck on the
surface of the ocean; and are not nearly so important or as
self-sufficient
as you thought you were. Which is an exceedingly wholesome thought,
and one
that may effect a permanent change in your deportment that will be
greatly
appreciated by your friends."- James S. Pitkin
