Need help on creating a material

Simon_____

hi i just took me model into substance to begin texturing and have already come in to an issue, im finding it hard to create this type of paint 

i was wondering if anyone has any tips or things i could do to get this look?

thats what i have at the moment, normally i work on tanks and mechs so car style paint is not something i've done before
