  Noel,
  Ready to install fuel feed/vent lines and seal my first strake.  Found a very easy way to cut/fit the baffles and bulkheads.   If interested, I can describe and send you pictures.

Dito in the pictures.

But now I'm getting confused...
I've heard that Jeffco comes in "fast and slow" hardners.
Does it come in "sealant" and "structeral" as well????

My 2nd hand kit came with Aeropoxy in a set of cans. 
(about pint size)
Is this the structeral adhesive that was mentioned for 
bonding the nonfuel part of the strake?
It's been in those cans for about 6 years, what are the 
chances that it's still good?

I hope to be finished sanding those pesky baffels to fit 
as soon as the temp's come down some.

Larry,

Ok - I'll answer....but since you said question for the
knowledgeable.....:o)

A: I think it's better to paint in conjunction with 
closing the strakes.

I like to chemical bond the Jeffco IF you have the 
chance to do so.  We did
all of the prep work on our strakes - ALL - and had 
everything setup to be
able to just do the Jeffco, and then seal the strakes. 
We used two coats -
and applied them within the chemical bonding period - 
it's been a while - so
I don't ember the exact # of hours.

We bonded the strake using Jeffco, glass and flox and 
cabo - which is what
was suggested by Scott Swing.  We used Aeropoxy for all 
other bonding - that
was not part of the tank sealing area - you will find a 
portion of the
leading edge to be in this 'area' - as well as the 
strake to the spar.

Jeffco colorant can separate - so I'd suggest really 
mixing the product -
but it is NOT problem - per Engr. Tech support at 
Jeffco.

Scott Swing has said something like... "build the parts 
out of ez, bond with
Aeropoxy."  I don't remember exactly what he said about 
aluminum - but I
know he didn't have an issue with it for the strakes - 
we bonded in the vent
tubes with Jeffco.  We did not bond in the aluminum for 
the fuel senders or
the finger strainers - those we used Aeropoxy - we 
covered them with bid -
and then like everything else-  Jeffco.

As always - contact the factory if you have any concerns 
- and contact
Jeffco Engr support - good people.

And don't try the above with just 1 or 2 people....we 
tied up 4 people for
the better part of 2 days.

BTW - I have a bunch of pictures if you are 
interested...

John

Question for the knowledgable,

Anyone have the difinative answer on these? 

Is it better to seal the tanks with the Jeffco right 
before you close the
fuel Strake or is it ok to paint the Strake walls days 
even weeks before you
plan on sealing the strake? Can you mix Jeffco with 
micro glass and use like
EZ-poxy? Bonding abilities with aluminum?

I haven't used this stuff yet...Sure smells good though, 
the wife is love
this stuff, ahh...the joys of building at home. Thanks 
in advance for your
input all.

Larry Lambert.
