Aluminum skin overlap

I have an aluminum joint across the front top curve. Would you overlap the top to the front so it sheds rain water or the front over the top so it sheds water going down the road? I'm using the carpet glue, but should I use something else at the seam?

Bob,
If it were me, I'd overlap so the water would run off while it is seting. I would get some urethane sealer like is used on automotive windshields and seal it with that. About a 4" overlap would work.
These are my opinions and I'm shure others will have other methods for ya.

....basically I agree with Steve, the carpet glue IMHO would not be sufficient, an automotive windsheild urethane or Sikaflex252 or something similar would be the trick along with a screw every couple of inches, also the lap should fall on a rib and the overlap should be at least 2+ inches

I'd do what Steve and Madjack suggest. I am using this product from Home Depot for all my seams. I had to order it online as it was not stocked locally. Got it in less than a week.

Would you not make a bend of about 2"-3" across the ends of each piece being joined, bend up and back on one, and down and back on the other, then connect the two bends together and clamp or hammer then together to make a watertight joint? If I decide to go with aluminum, I hope to be able to buy in one long piece and I'd need over 20' to cover from back to front.

Interstate metals up here in the Portland area joins the two sheets with a really slick seam. Norm P showed me his tear and the seam was almost completely flat. It looked great. Check his gallery in the hall of fame. Maybe your supplier could do the same.
