Re: Clear coat ruined it

I think you have to start it all over again! But my guess is that the color coats and the clear coat is not from the same manufaktur.

Or you waited to short time. Normally when spraying, wait 5 minutes between each spray layer, but wait 15 minutes between color and clear coat layer.
