Default Spraying bare metal

I have some metal sections to paint up.
I going to degrease the metal first.
Before I do a coat of paint, am I correct in saying i need to use some etch primer first ?

Depends on the paint, finish and what environment the sections will be in.
e.g. Hammerite goes directly on metal, couple of coats good to go.
The paint primer will need a key. Etch primer provides this by eating into the surface of the metal.

id suggest you do use a etch primer ...bites onto the metal for a better chance of it all lasting etc

you can lash normal primer straight on . it wont bubble up or do anything strange but wont hold up to abuse so well

Etch primer is definatly the way to go, ive used normal primer on bare metal only to find a few months down the line the paint starts lifting then rusts!
