Which trailer paint?

[Giles1]

Got a home built trailer to paint for bale carting ,made from bare steel. Got to the paint stage hence the question. Needs to be durable ,flexible and keep its colour for a few years. Advice welcome. Been told Agrideck made by a Dutch company (BICCS) is good, price certainly is......

Paint is only colour tbh, its what you put under it that counts.
i use jotun jotamastic 80, its a 2 pack epoxy primer, the local shipyard uses it as a primer on the ship hulls, i reckoned if it was good enough for salt water it was good enough for the jobs i do.
i find it an excellent primer, its not the type you sand down before a top coat, once its nearly dry i put the colour on.
and as for colour, i use 2 pack (2k) car paint with the colour chosen of a British standard colour book i keep.
