1970 GTO endura Bumper
I'm restoring a 70 Endura and have read an exhausting amount of info on how to prime it. Some say no epoxy some say epoxy is ok, this is an original bumper, and I already repaired the cracks with the correct 3m repair kit. It will get driven. So now what? I'm not paint brand loyal. I will finish the car off in white with base clear. Do I need flex agent or not. I need someone who has actually worked on one and has success. thanks

No flex agent.
Use SPI epoxy, it is flexible. Many other epoxies are not. You can use the 3M repair material under or over the SPI epoxy. The SPI epoxy block sands very well. On my front bumper, I sprayed 5-6 coats 30 minutes apart, then blocked until I hit high spots, then sprayed more and did again. A few spots were too deep to fill that way, and the skim coat of 3M material was needed.

I used the SPI also and loved it.
