Surprised to hear this as Aviaid is certainly a well known product. But when it comes right down to it, it's like any job, the person doing the actual job has control over the outcome of the project. Unless there is some solid QC after the fact the consumer is going to become the Guenea (sp?) Pig. That being said Tig welding is more likely to have small pinholes than Gas welding, although in the hands of a good welder, Tig Welding is a work of art. Nothing exemplifies quality and attention to detail like a tightly stitched weld bead throughout a project.
