Dan,

 

In the builders workshop on my ES, we used Hysol/flox around the fuel tanks and Jeffco/flox everywhere else.  They were planning on testing the Jeffco with the slow hardener for fuel resistance.  If it passed, the factory was going to use Jeffco/flox everywhere.  That's been two years, not sure what they're doing now.

 

I will say, that when I closed the wings, Mark Manke was called over to inspect the sanding.  He pointed out several places that needed more sanding.  Of course we did that.  He also came over and inspected the applied Hysol/epoxy/flox before we lowered the wing skin.  They seemed to take the closing very seriously.

 

I'm not sure who the buildshop manager is now or whether they have the same procedures in place.
