??? Where you see this?

And brand of paint?

could you have wandered into the house paints section by mistake? 

Seriously, any further info, and what you think of it's painting qualities would be useful

british paint's ceiling white ., haven't used it yet

British Paint is a brand of house paint. Are you considering using it on your models?

is that bad??

I have used those 'tester pots' of colour from the household ranges, but only the earth & sand tones on diorama bases & never on an actual model.

The paint pigments are more akin to sand grain sized, so aren't suitable for models.

House paints are not for plastic kits. LOL!
