Thanks for the compliments everyone. Actually the roof gutters are there because the roof is a seperate part of the body from the two side panels. They tack weld the roof on and put those strips there since it is considerably cheaper. Look at a few other cars, they don't have those gutters, especially cars with targa tops.
The place where everything is being done at is my fathers shop, and they do very good work. The gutters were welded to stregthen the ends, and then filled with "long and strong" which is a form of fiberglass. Very little bondo was used except for the final finish work.
Lastly, the gas filler is inside the car, if you look at the other album on imagestation, it has where the filler is located. Thanks again.
