Cheers guys.
Not seen anyone else throw this out there but "plastikote super" spray paints are very good it seems.
The yellow gloss i used on my other g36 went on well and the finish has lasted well considering it's yellow on black and this matt grey also went on well.
It's like £5.50 in wilkinsons(where i got the yellow) or £7-£8 in b&q. They are on 3 for 2 at the moment at b&q even on the website so even with delivery it's still cheaper than halfrauds/krylon.
I think the only usable matt camo colours are going to be the icecream(tan), the grey and black but still it's better than nothing I'm definitely going to get some of the black for when i spray my deagles in a couple of weeks.
*edit*
There's a chocolate matt as well so only really missing an od type colour
