It is not strictly the warping, but the expansion you need to watch for. I once sheathed a boxcar and then painted it. The siding expanded to the point where the glue was broken, and I had to trim two board widths off to get it back in place -i.e. the siding had become wider over all...
You might want to try chalks or weathering powders that won't add any moisture of any kind to the wood. MR has an article in July 2010 about avoiding distortions in wood by colouring with chalks.
