I have repaired three pair of rusted out cowl on 28 and 29 vehicles. You are definitely correct that this is a problem spot for 28/29 model A's due to years of use on questionable roads. I cut out the exterior panel in the shape of a triangle and butt weld in a patch of the same gauge. The repairs work well - see attached pictures.

Is that patch (2nd picture) overlapping the original metal???  If so, what do you do to stop rust getting into the overlap?
