sits on back to bright steel. Centre the dome, tack it at four points opposite each other so it does not pull to one side, then weld round in short runs. On a thin wall, keep the heat down and let each run cool. If the dome is outdoors and sealed all round, drill a small drain hole at the lowest point so condensation can escape.\u003c\/p\u003e\n\u003cp\u003eDegrease, then prime with a zinc-rich or metal primer before painting.
