, i was going to say have a look at this, used it on a tvr i had and seemed to do the job,
don't know about matt finish though
anyone know of a tough nightmare to remove paint that would stand up to anything but an angle grinder?
I need something that’s dull matt and isn't going to come off, ideally brush or roller on. Was thinking about paints used on boats, car stuff is
just to wimpy for my use.
sorry about that ...hit the return button a bit quick , i was going to say have a look at this, used it on a tvr i had and seemed to do the job,
don't know about matt finish though
It says on the link that they do a semi gloss finish option.
yip that looks good stuff
but again I kick myself for forgetting to mention that its going on GRP and I need some colours like yellow, green and brown 
sorry
Frost are selling a new POR-15 topcoat called hardnose paint.
http://www.frost.co.uk/item_Detail.asp?productID=9514
Black, Yellow, Red, Grey or Blue
Don't think it will stick to grp unfortunately.
2-pack (professionally sprayed, insert isocyonate warning here etc.) would be toughest of the normal choices.
cheers, looks like some kind of epoxy type paint, think I have a use for that too.
Get some boat anti-fouling.
Will be cheaper and tougher than POR-15 which I only found effective when sprayed and the surface prepped and super clean.
