Hi Mick,
yes, I can confirm all you said in terms of drilling and deburring and the mental state it gets you in as well as the number of rivets...
However, I´ve identified a few areas where I´d have to make do with blind resp. Cherry-rivets
because these particular areas can only be accessed from one side. An example is the floor pan to be riveted to the knee hump supports / stiffeners.
Best,
Marcus
