I would think that oil-based Rustoleum would be OK.
Just roll on, leave dry a day, then apply vinyl.
You can tape off the area with blue painter's tape so the patch is nice and straight.
Remove that right after painting.

Latex based paint will flake right off....and vinyl will not stick to it.
Seems like a lot of work for what is supposed to be only a temporary substrate.

Krylon fusion in spray cans would work

Look for a paint that sticks to polypropylene. That would be your best bet. They often list the type of plastic on the can.

I know you don't want to hear it, but nothing you do will work for any length of time. We're trying to get ink to stick to it every minute of every day. It's almost all we do. It's an uphill battle on coro.

Polypropylene and polyethylene are commonly used in packaging food and adhesive partly because they release well to come clean.

I've lettered coro with one shot, so I think any good oild base would stick.
But my preferance would be Krylon Fusion.
