Hi guys and girls, I've applied clear coat to a tank (it's for presentation, so it's can be painted again), and after almost 3 hours it still has this fogginess on it. I used spray can, it's reliable for me cause hasn't caused any problems, but this suprised me! Yeaaaaah!! good weather conditions 20 C, no humidity today, apply two light coats at first, plus 2 final coats after 5 minutes to complete it. Had some extensive overlaps which create those tiny waves (can't remember how it's called) but my main question is about this grey shading which has been created. Do you have any ideas what went wrong?
