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.
