Dulux Duramax Multi Glitter Spray Paint

I love the multi glitter effect but this is very hit and miss – I have spent an absolute fortune on this spray paint in the past. When it works it's great..when it doesnt it ruins hours, sometimes days of hard work, hundreds of dollars worth of paint and makes you want to cry. I use this on parts of my car both interior and exterior.. when it works looks absolutely awesome, but when it doesnt it turns white, or you cant see the Multi color and you never know till its dried what it will do.

Most recently i used it on a couple of projects im doing for someone really close as a surprise for xmas.

Well one which was white turned the thing yellow, you couldnt even see the glitter at all once dry... the other was once black is now white ..

Completely ruining both and my days and days of prep, finishing and hard work

I want to cry!

This is very expensive spray paint made by a well known manufacturer and while in the past ive just accepted it and removed everything and started again even ruining the paint work and look of my expensive pride and joy, this time its worse than its ever done it as if its white not glitter o even double checked i hadn't picked up the wrong can as even the grass tuned white around the project i was doing, i am now going to have to redo everything and i am running out of time and i really really cant afford to buy every thing again
