I will second, or is that third, Dan's comment. After several years worth of battles with leaks I just could not stop, I cringed at the idea of cutting big holes in the rear baffle. I finally bit the bullet and did the big cut in all five bays. It was the best decision I could have made. I only wish I had done it sooner. It sounds scary and even a bit rediculous to cut a great big hole to fix a tiny leak but it really turned out to be the best choice for me. It really was an easy fix. So easy I did it twice in two months on the same tank (a long story). Vans has a kit just for this. Call them and order it. You wont regret doing so.
