Cool.:thumblef: Key is to sand off as much as possible with guide coat. The polyprimer can have a tendency to chip more easily if you leave a bunch on there, since it is basically sprayable filler. I sanded the featherfill to 320 and then started my with 2k primer. Once I got all the sanding scratches blocked out with 400-600 I shot a final coat of reduced epoxy before basecoat. This 50% reduced coat of epoxy is great for getting a uniform color for the basecoat. As a sealer coat, the epoxy is great for stone chip resistance since it is more flexible than regular 2k primer or regular sealer. Little to no shrinkage either (at least for the SPI epoxy)
