REFLECTOR: Jeffco Question.

[John Tvedte]

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.
