Hi Guy’s,
The hinges are difficult to machine - drilling the welds out of the studs was especially tricky and I ended up using a cobalt drill. Welding the new studs in also has its problems as the studs need to sit flush. I am going to see a pro welder about this as the penetration of the weld is critical. Get it wrong and the doors will fall off. I will post some pics up of when it’s done.
Andy, to answer your questions…
Always apply zinc primer direct to bare metal. Never over a rust killer / converter.
It keys well to bare metal especially if the metal is scuffed with 800’s wet and dry or green scotchbright
Zinc primer will not work on top of any kind of paint – gloss or etch primer.
Hope that helps and if you have any more Q’s, just ask or drop me a PM
Pete
