Ok first time Plastic dip user, did my wifes mirror covers in white, looked good and then put on 3 coats of glossifier and 24 hours later it's still tacky, how long will it take to cure ?

I have them sitting in the house so it's not hot or humid.

 

Mine was still tacky a day and a half later when I did my roof rack cross bars... Try putting them out in the sun, worked for me. Baked it on, I guess. Was my first time using glossifier... Normal PD doesn't seem to have that issue.

 

The Glossifier should dry pretty quick as long as white PD is 80% to dry. Make sure you don't over spray with the gloss. The gloss is for looks not for coating

 

My roof took a few days in the sun to bake it on and be rid of that tackey feel. Also depends on how much you used.
