Hi Rusty;
    Yep, you've got it about right. They are exactly like the main tanks, but located in the entire outboard section of the leading edge. I also have fibreglass wingtip tanks as well, but they seem to be fine. I used the standard "ProSeal" that Van's sells. I had to make a few variations from the main inboard tank design to accommodate plumbing, but the design is for the most part as close as possible. I used the same "ProSeal" throughout from 2 cans bought at the same time. I actually still have a little left over which I keep in the beer fridge. It is at least 4 years old and while I wouldn't use it for a critical application such as fuel tanks, I do find use for it occasionally on odd jobs and find that it hasn't appeared to have deteriorated with time.

  I can't recall how your aux tanks are built.  Are they similar to the main wing tanks, but outboard, maybe near the tips?  Did you use the standard "ProSeal", or some other sealer?  So far, my tanks have held great, but I've never found any water in them either.  
 
Cheers,
Rusty (far fewer tanks than Todd)
