2k on trans am urethane nose

S

I am painting a 77 trans am. I primed everything with spi epoxy. I am using spi 2k primer on the metal body for blocking. I am just wondering if I can use the SPI 2k on the urethane nose cover and urethane rear bumper cover or do I need to build them up with epoxy and block that down? Needless to say the 2K on the bumpers would be easier to work with but I am just wondering if the 2k will have enough flex to use on the urethane rubber bumpers?? What do you guys suggest? I guess the same would also apply the wheel well spoilers as they are the same material. Can I use the 2K or do I need to stick with epoxy only on these items.
I will spraying prospray basecoat and spi universal clear for my top coats in case that matters to answer the question
 
epoxy only would give the best results, if your do use urethane primer keep it thin!!! I've done those urethane noses in epoxy only and it is amazing how durable they have been.
The rear wheel well spoilers are magnets for rock chips-epoxy is your best bet.
