Hi Jim thanks for the concern.
After the first couple of times it has rained since I put it on, it has got steadily more and more water tight, to the point at which now even with the latest torrential down pours it does not leak one little bit. Well happy much better than the old holey roof...
By the way what went wrong with your Sherman ?
Tanks in Town was my first time there and I can't explain what its like, you just have to be there.......
Shame you did not make it to T.I.T.'s would have been great to see 8 Sherman's in a row, where else would you see that......
