Hmmm.... exactly what is happening in the photo and why and what and any info would be noice ('fixing an F-22' doesn't wash) but I digress...
Another quotable quote quoth them...
USAF praises early performance of Lockheed Martin F-35 06 Nov 2012 Dave Majumdar
"...Sgt Skyler DeBoer, a senior maintainer with the 33rd Fighter Wing, who has previous experience on the Lockheed F-22 Raptor and F-117 Nighthawk programmes, says the F-35 has the edge on the Raptor. "Compared with the [F-22], this programme is way ahead of where the [F-22] was, software-wise, aircraft-wise," DeBoer says, "Lockheed has made great strides with this aircraft." DeBoer attributes part of the improvement to better maintenance training. F-35 maintainers have received far more extensive instruction at this early stage of the JSF programme than on the F-22, he says....
...Additionally, the F-35's stealth coatings are much easier to work with than those used on the Raptor. Cure times for coating repairs are lower and many of the fasteners and access panels are not coated, further reducing the workload for maintenance crews. According to Lockheed, some of the F-35's radar-absorbent materials are baked into the jet's composite skin, which means the JSF's stealthy signature is not easily degraded."
