I am not sure what materials take paint best but mine is a pretty standard tarp material. It gets stored folded up and the paint has started to crack in places, in irregular patterns, but that adds to the camo effect as the olive green of the tarp material shows through as long random cracks, which adds another dimension to the overall effect. My tarp seems to be made up two ways of adding the paint; one is long (18" to 2') wavey lines about a spay line width wide (3" or so) usually have a kink in them & the other is patches of paint finely sprayed on from further away. Another way of looking at it is it looks a bit like the stripes on a tiger, that help to conceal it in the long grass, but a bit more random, if that makes sense. As with all camo it's about breaking up the ouline & the longer wavey lines on mine seem to work better than the quite short blobs of colour you get on DPM & other camos. There are some other threads on BCUK about painting tarps but can't remember how much detail they go into; i have also seen ex servicemen on here mention it a few times, so maybe some of the could tell you how it's done as maybe the army has developed some ways of doing this. Interesting subject & sorry that the OP's thread has taken a detour... but I hope they find this interesting.
