The little bit of research I've done in the past about using silicone bronze for patch panel work is not a good idea. Something about the metals expanding and contracting at different rates causing a ghost lines in the finished paint. Maybe not a big deal since your just doing little holes. No experience here though so maybe someone else can chime in.
Nice job with the metal fab BTW.

In one of Ron Covell's videos he uses a step bit to drill all small holes to a specific size and then use a metal punch to punch out a bunch of small round 'plugs' to weld in each hole. Rather tedious, but it works. In his example the car was an antique race car that had a custom formed body originally and they wanted to preserve as much of the original sheet metal as possible.
