Whenever we do a butt weld on a major panel, we follow it up with a scoop of fiberglass jelly. This is used to be sure that there are no pin holes for rust to use as a breeding ground. 99.99% of it get sanded of before sealing.
Tim, just curious why you wouldn't use AMD's full qtrs, seems the amount of work to install the 1/2 skins would elate to the same amount of time/money to install full qtrs,...the benefit being IMHO a more structualy sound car, with less chance of the welds possiblely breaking down the road as the body will see torsional loads......

At our shop, the labor cost wouldn't change regardless of which way we went. But, the cost of the full quarters is substantially more than the skins. We guarantee our work for the life of the original customer. So, we just saved him about $1,000 on parts.
With correct penetration, a proper butt weld is stronger than the metal around it so there is virtually no chance of the weld breaking.
