Haha, no.
I didn't ask them to, to be honest.
I managed to get away with it as th person they were for wasn't too fussed, as long as they looked good at speed.
I did try to even paint over it with some old paint ( you know, when you get a bit left in the bottom when its been stood for a bit) but even that didn't get rid of if.
The colours were white, flo'green, and black. Instantly noticable because of how thin the paint is, its almost water consistency. But by the sound of it, it is a full batch.
They did say that if you've got a credit card (which I haven't
) and you get some of the faulty batch, they will sort you out with either replacement bottles, or a discount, if you contact them directly and let them know of the problem.
