Ive got some surface rust in the floor of my Traveller ( and a scrape on one of my wheelarches - but one thing at a time), I will (eventually) wire brush this off then treat the metal - and this is where my confusion starts...
Firstly - regarding initial treatment aand primimg,
Ive seen reference to rust converters and acids - should this be the first application? which one does what job? should I be wary of compatabilitywith following applications of primer / paint?
Then, do I use a primer

if so Ive seen the following mentioned:
Red Oxide primer
Zinc rich primer
and Etch Primer
...which is best to use for what ?, is more than one needed?, are any of these incompatible with paint?
Then having primed - do you require any sort of undercoat ?, or is it straight to the paint finish?
If straight to the paint - how many coats? - do I use a straight forward aerosol(Ive heard of cellulose and 2 pack...)??
Hence my confusion

I'd be grateful for any advice....!!
