Many misconceptions exist about how often the Bridge is painted. Some say once every seven years, others say from end-to-end each year. Actually, the Bridge was painted when it was originally built. Until 1965, only touch up was required. In 1965, advancing corrosion sparked a program to remove the original lead-based paint (which was 68% red lead paste in a linseed oil carrier). The removal continued to 1995. In 1965, the original paint was replaced with an inorganic zinc silicate primer and acrylic emulsion topcoat. In the 1980s, this paint system was replaced by a water-borne inorganic zinc primer and an acrylic topcoat. The Bridge will continue to require routine touch up painting on an on-going basis.
Yes, put an oil-based primer on first as a bridge, then apply the acrylic paint.

All the information I read on Tinners paint refers to it as 'anti-rust' exterior metal paint . - I certainly wouldn't put a latex primer on anything outside. I would use Kilz original as a primer.
Unfortunately primer is designed to prevent this, but if you know what kind of base the primer is (alcohol, acetone, water, etc., look at the primer's directions for its recommended solvents to be used for thinning or cleanup), you can try using a rag with that thinner to try to scrub away the primer. However, try this on the original paint first in an inconspicuous spot (the bottom, perhaps). If you're unlucky, the original paint may be damaged because it uses the same base as the primer, in which case, DON'T use this method.
so the paint wouldn't need to be done again for a long time
It takes a bloody long time to paint.
They paint it every month so that the bridge doesnt collapse. It hasn't been painted for three months though so please be aware.
Look, I've been painting for a long time and all I can say to you is Good Luck. You will never remove the primer from on top of the paint. Sorry.
No, it is not recommended to mix primer and paint together as it can affect the quality and finish of the paint job. It is best to use primer as a base coat before applying paint.
