Easy way round pink staining paint.
Buy pink playing gear. So it might still stain but your never going to know anyhow.
My own thoughts are if I'm fireing paint that stains tough sh!t.
If you feckers didn't wipe so much the manufacturers wouldn't have to make the paint so thick and sticky.
Oh and I know exactly what paint it is that is staining. I'll give you a clue its not fully biodegradeable and the foresty commission won't let it on thier land.
