I know Doug's ally welding is superb. I can't see why steel should not be as good. I have a sump and gated baffle from him in the garage that will be going on my 500 horse track car engine. I have not inspected the welds but will have a good look and if needs be get the mig out for insurance
All the dealings I have had have been very good and a true gent when I met him. He aint a rip off merchant and actually very helpful.
