Yes..sometime G2 could be "too tight" and give unwanted results
Now you can understand better my car-fender video (you asked me ;) )
My target was to have a G2 junction between fender and car-body
I've extracted curves from G2 blend surface
modified points of extracted curves withouth touching G2 points close to the body-car
sweeping all to get a fender that have sections with G2 continuity
at the end of the video you can see i did a close-up showing a perfect junction (G2-based)
