comment SU(3) gauge invariance in QCD
Uhm, I think I sorted out... Most probably I missed a commutator in the interaction term, which accounts for an extra term in the transformation of G. More important, as you suggested I should keep everything to first order, that should be the way to transform correctly the field strength tensor. I still don't know how exactly, but now I should be on the right way... Dropping the problem now for lack of time, but at least I saw the light at the end of the tunnel. Thank you.

comment SU(3) gauge invariance in QCD
Can you elaborate the expansion? Is the usual expression for the derivative of an exponential not valid for matrix exponentials?
