Epoxy or Urethane High Build... what's next for me?

Thanks for the feedback everyone... So, here's my plan. Your additional comments are welcome.
  • Sand down as much of the rattle can primer as possible stopping at 180 grit. (I know for sure i won't get it all off b/c some panels are fully covered... it does sand incredible well though)
  • Spray entire car with SPI Epoxy Primer (white or grey)
  • Spray entire car with 2X Urethane high build primer (SPI... or is any brand fine?)
    • Block, block, and block again... stopping at 400 grit :)
  • Spray entire car with thinned SPI Epoxy Primer (as a sealer) (white or grey)
  • Then move on to the base/clear & buff
Car will be a bright red... looking at Viper Red or similar. Not sure if I'll use the SPI universal clear or something same brand as the base paint.

Anything I'm overlooking?
Sounds like a good plan. I love viper red. Just remember one important thing. A paint job can be no better than the prep work. A really nice paint job has a zillion hours of prep behind it. Good luck. Looking forward to pictures. Some white stripes would look good with the Viper Red.
