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?
I would keep the brands the same. If you go with spi epoxy go with spi 2k also. And follow all the directions and clean clean clean clean. Prep and CLEAN! Haha I'm not a professional either this is my first "real" paint job I painted my dart with tractor implement paint 16 years ago does that count? Lol sounds like you a have a plan. If you have any questions text Barry at spi his number is on their website he has helped be tremendously day or night mon-sun no joke. You dont have to start with 180 to remove the old primer you can go courser to get it off just finish at 180 before you spray your epoxy!
