Just wondering if anyone has removed fiberglass wing tanks from completed wings. Mostly wondering what chemical can dissolve the adhesive used to hold the tank to the spar (if any) without damaging any of the parts. Can anyone help here? I need to repair a tank and coat the inside while I've got it out. I found coatings in the archives.    John Sandt ((at) beautiful Death Valley, CA)

I don't know of any chemical that will dissolve the silicone that is 

used to hold the fuel tanks in place.  I unfortunately had to remove both 

tanks from the wings.  What I did was to turn the wing upside down and using 

an exacto knife I carefully cut out the silicone from the rear spar.  Use 

great caution here so as not to damage the spar.  You may be able to use 

some knotted fishing line to cut the silicone like a band saw once you get 

enough of a gap between the spar and fuel tank.  Remove the silicone that 

you can from the bottom of the front spar-fuel tank gap.  Once the rear spar 

is loose rotate the tank from the rear spar to tear the remaining silicon 

from the front spar-tank gap.  Then lots of hand work cleaning off the 

remaining silicone that is stuck to the tank and spars.

I had to remove a 13 gal fiberglass wing tank from a KF2 wing and it was 

held in place with stuff that seemed almost ike rubber cement to me. It 

was probably silicone adhesive, butt it didn't adhere to surfaces so 

much that it required any more than rolling it off onto itself. It was 

easy to remove perhaps because of a corrosive resistant coating on the 

spars (varnish or polyurethane?). Maybe the builder of my KF had learned 

of a method to allow for easy removal. You indicate that you may have a 

more agressive adhesive. Let us know what you find.
