Yes the dimples were a big difference but not enough to keep me from having to work as a bondo boy. I Hysol'd my left side stringer today but that was it. Guess I have been lucky with my rivnuts. I did have one spin on me long ago but it was one of those smooth aluminum ones and I should have known better. I restored a 65 Corvette and a 70 El Camino in my earlier days and was able to use rivnuts in places that made it so much easier to work on later on. (Corvette guys are probably rolling their eyes reading that - sacrilege!!).
We are doing combat snow over here today. Woke up to over 20" of new snow and after I completed going over all that I have to plow (3 hours for a normally 1 hour job), I looked at the area where I started and there was 6 inches of new. Sure interferes with the building of my plane!!!
