"...On the other hand, builders who use no primer may be motivated by many factors including impatience, penny pinching, laziness, or simply a complete lack of knowledge about the effects of corrosion on aluminium. But whatever the reason, you can be virtually guaranteed that, having used no primer, they will encourage you to do the same. It obviously makes them feel better if they're not alone..."
Not necessarily disagreeing with you on primer but implying people that choose not to prime their airplanes are lazy, cheap, impatient, or lack knowledge is uncalled for. There are thousands of decisions in building your own a/c, and just because some don't agree with your opinion, they are wrong?...Really?
Yes, after reading as much as I could and deliberating a lot, I chose to prime with the same stuff Van's uses on the QB...I did call Van's to get their opinion, too. They asked if I was building an airplane to last 40 years or 80 years. I guess that about sums it up...
