SPI
Their epoxy flat out makes PPG's dplf look stupid.
Any single stage urethane would go right over the epoxy for a nice "bulletproof" finish.
PPG's would be DCC
Dont remember the SPI single stage.
And yes epoxy can go over 2K urethane primer, but on bare metal nothing NOTHING comes close to epoxy.
