Prepping bumper fillers for paint '77 Supreme

Hi All,

Did some searching initially, but didn't come across a definitive answer. I'm replacing the front bumper on my '77 Cutlass Supreme, and this includes the bumper fillers. I acquired decent condition bumper fillers to use with the replacement bumper, but need to match the color of these fillers to the paint on the rest of the car. What is the best recommended way to prep these malleable fillers for paint? Simply a scuff and shoot?

One of the fillers in question, I acquired a red and yellow filler, while my Cutlass is blue:

I should note that my Cutlass is by no means a show car or anything close. I'm just hoping to be able to roughly match these fillers to the rest of the car, and not run into issues with paint adhesion. Any advice is greatly appreciated.

The other day my oldest Granddaughter who lives in Virginia sent me phots from 1 1/2 to 2 years ago when we took my just painted 72 Cutlass 442 to a local car show! Nice photos she took!

Expoxy primer shelf life

Finally getting to the point where I can start priming some parts again.
I have some open Grey primer 90% full, that has been sitting about 2 years.
And a gallon of unopened black also sitting around 2 years.
I heard that the activator that is open is ng after sitting that long.
Am I asking for trouble using paint/primer that has been sitting that long?

I see shops with tons of open cans for color mixing, I Imagine it must take years to use up some of the colors.

Thoughts?
