I talked with the TCP folks and they suggested that I should have sprayed the white primer heavier and that I could go ahead and spray more coats to get hiding. I was spraying correctly, maybe even a little heavy. I had some light runs/sags, so couldn't really go much heavier.
I didn't fully trust their advice so I decided to follow advice I got to spray a grey primer to ensure hiding and then recoat with the remaining TCP white that I had. I sprayed 2 medium wet coats of ppg shopline epoxy grey primer and that has given the truck full hiding - no noticable bleeding.
I'll block that down with 320 this week and shoot two medium coats of white over the grey. I plan to not sand those last two coats of white and spray sealer and color within the recoat time to finish 'er off next weekend if I get decent weekend weather...
