There's a website some guy used but I can't remember what it is, I'll have a browse and let you know.

Halfords have all the data to mix it up properly, just a bit of a lottery if the person doing so REALLY cares about getting the weights exactly right or slops it in "about right".
nice one. Order placed
Id rather not deal with those chimps tbh. Lol
I got my colour mixed up at halfords when i painted my door strips, £20 for 300ml i think?
£20 FOR 300ml " you think ? " . I hope you thought wrong , that's an outrageous price
