Hi Steve,
I believe what you are seeing is what I have been calling print-thru,
not heat/expansion related. Print-thru happens on foam cored surfaces
that have something glassed to its back, like the fiber glass
reinforcing for your fuel filler neck. As your plane ages, you will
find more print-thru on the fuse and wings.
regards,
Terry Seaver

Subject: Europa-List: Moving fiberglass
This issue had come up before some time ago and I need my memory
refreshed. Am flying around in the hot AZ sun and differential
expansion is rearing its ugly head. This is especially true on the
fuselage right around the area where the fuel filler maniflod is
attached to the inside. Some very prominent waves have developed in the
skin here. I am hesitant on filling these to smooth things out. I am
assuming that it is reasonable to expect that things will keep on
moving through temperature cycling. Does anyone have any history out
there with flying in very hot weather and having the fiberglass move
around? Have you found this to settle down after some time? Has
anyone come up with a different mounting routine for the manifold after
getting the ripples?
