Hi Guys, The first tank I built was a header tank made of fiberglass. I holds 22 gallons and never leaked. Then Dana came along and built me some aluminum wing tanks using poop rivets and ProSeal. And from .032 aluminum sheet I might add. These tanks are awesome. The Proseal is amazing stuff and covers the pop rivets and seals the tank like the dew covers Dixie (southern terminology). Than Proseal is very flexible and has a rubber like consistency. In my opinion, the only way to build a tank. By the way, I still have my header tank even though I am not going to use it. I would offer it for sale or to the highest bidder but I custom built it to the width of my widened fuselage so I doubt there are very few KR's this tank would fit. If you are remotely interested let me know. Here is the link to my header tank: http://mywebpage.netscape.com/n886mj/tank.html sorry but there are no photos of the finished tank there but it will give you the idea how I did it.
