Scippy , if you were using Epoxy , say................Shell like skater uses or Plasco with a pot life of 126 min 's or more .....at 70 degree's you would be able to get 5-6- or 7 layers at one time mixing the resin with a little cabosil for a thicking agent to help prevent gravity from taking over and to tell you the truth Epoxy might cost more but has so many more options . strength , work time , and no stank .
