He was a world class structural welder who could boast of a welding record unparalleled in the shipyard. He maintained a 0% rejection rate for over 12 years, in an industry where any rate below 5% is considered good and 3.2% is average.
The good-natured compliment that was heard when he completed a welding job, "You can paint that one now" referred to a completed welding job, meaning no defects were found. A perfect record of 12 years certainly justified such praise. Peter's superior hand and eye coordination was evident in his favorite hobby as well, having won several trophies for shooting pool.
