the amount of time has not got anything to do with it , if it drie's for a hundred year's it would still do it , if you try it like I said above it will fix the problem and one more thing that I forgot to mention is that if you push whatever you are working on outside in the sun the primer will dry as fast as it hit's the area !!
let us know how you do , am getting my cab ready to paint right now too ,,
