Project 66 Valiant Drag Car

Nice job, bloke........How is it that stuff ( welds, cage piping, etc) hasn't gone rusty ????
Here, bare steel goes rusty in 1~2 days....very hot and humid here....today is was 90*F and 85~90% humidity.....just sweat standing there doing nothing.
Humidity is only 30-35% right now so no rusting going on
