All valid techniques. I have used the IP 2000 instead of the Awl Grip High Build Primer. This way you can combine the barrier coat and the high build steps. It is cheaper, sands well and fills pin holes. You still have to compete all repairs and fair the surface before you apply the 2000. After you sand the 2000 if you still have any pin holes or swirl marks you can thicken the 2000 with Colloidal Silica (Gougeon 406) and apply with a spreader. You can't expect to fair with a finish. Here is a Santa Cruz 70 that is currently in our shop primed with 2000. In the second picture you can see a section that was filled with thickened 2000. The owner sent his boat manager to help sand the 2000 and he edged the DA and we had to redo the entire area he sanded with the thickend 2000.
