It's all in the application. I'm very careful about "kreeming" a tank and follow the direction to a tee. I also let the tank dry several days before filling it. So far I have had no failures. Poor adhesion comes from poor prep and it's all in the prep work. Still I always run a filter on the output to make sure no small particles get into the carb.
You can neutralize the rust with the Yamaha solution but it doesn't stop the rust from forming over the winter again as far as I know. I guess it's ok if you fill the tank to the brim and put a stabilizer in it.
The Puch is the worst. Not only does it rust in an instant but the tank is an integral part of the frame. So you get a leak about the same time your frame breaks in half. Who came up with that idea? Go figure!
The best solution is my Towny. It has a plastic tank!
