Camouflage Help

[Journeypilot]

Hi all,

I'm new the forums, have been Geocaching for about a month now and thoroughly enjoying it!
I want to put a mini Geocache series out, I've put a lot of thought into it however I'm stuck on one part. One of my containers is fairly unusual in its shape, it's brightly coloured and I'm wanting to Camouflage it with something. It's a plastic container so of course I've looked at using the Krylon Fusion spray paint however it's quite expensive and the cans are way to big for what I need now and for what I can see me ever needing. I've been toying with the idea of trying to cover it in Duct tape of various colours to create a camouflage effect however whilst most of the container is a basic enough shape for the duct tape to work well there is one section which is very unusual in it's shape and I don't think it'll work.
Can anyone recommend me a paint that would withstand the elements and be a reasonable price for me to do the part that duct tape wont work on please.

Thanks!
