I wanted to wait 5 days , but i only waited 2 , you can tell right away when sanding if its time , or by using finger nail onto tape of overspray ,depends on the temp too , but its best to wait as long as you can , so several coats can breathe out and dry , on my next cue I make im thinking of try PPG Deltron , i hear its excellent and less money , although i had a friend give me a gallon of Dupont , I had a cuemaker friend tell me id be fine because of expierience spraying cars , well its a little diffrent :smile:
