I've read all the posts, several times, regarding mylar seal replacemate. My
LS3-A needs the seals replaced and am considering doing the job myself. Is
this something a reasonabley compitent person can do on his own, or should
this be left to a pro? Your input would be appreciated.

Our LS3a has internal seals, which will need replacing soon, and no mylar.

Which is the best way to go, internal seals or mylar (or both) and why?

My gut feel is that the airfoil wont benefit much from mylar provided that
the hinge gap is sealed to prevent air leakage from the lower to upper
surface - as is the case with internal seals.

We also use a textured duct tape on the lower (hinge) side of the joint. I
presume with mylar, the hinge tape would fall away.

There is currently some "raised bump" (zig-zag like) tape just upwind of
the joint on the underside. I doubt this helps and if it does, the
textured hing tape should have the same effect. We will probably take off
the bump tape when we do the hing seals again.

But how much work is install internal seals verses mylar?

Thanks
