What is the best method to paint a plastic grid on a door that outdoor paint doesn’t adhere to, would clear polyurethane provide better durability or is there a different solution to try?

What would be the best material to use for painting the grid on this door? I used outdoor door paint, but it doesn’t seem to be sticking well to the plastic grid. I can easily scrape it off with my finger 🙄… Do you think clear polyurethane would make it more durable, or is there another option I should consider? Thanks for any advice!
Consider using Emerald Urethane paint for your project.
For optimal results, start with a quality primer followed by Emerald Urethane paint. The ODL white plastic frame may pose a challenge due to its composition, but a polyurethane topcoat can assist in achieving a durable finish.
Give the plastic a light scuff with 120 grit sandpaper before applying the paint. This will ensure better adhesion. My go-to choice is emerald for all my trim work, and sometimes even for cabinets.
While Emerald is a decent paint, a more recommended option for doors and trim would be Command from Benjamin Moore. ‘t forget to lightly sand the surface beforehand for better adhesion. A good choice for a primer would be Stix before applying the final coat.
For best results, make sure to use alkyd primer and paint after properly prepping the surface.
What type of paint and primer was used?
Using primer before painting plastic would have been more effective. At this point, it’s not going to make a significant difference since there’s already a layer of paint on.
Start by applying a coat of Styx primer.
Appreciate all the help, guys! I kind of rushed into it without priming or preparing the surface. I’m considering giving it a light sanding and applying one or two more coats, maybe even a polyurethane finish for fun…taking a chance and crossing my fingers!
There’s a kind of oil in the plastic that prevents it from becoming brittle and breaking, similar to vinyl siding. Once you remove the existing paint, clean the surface with rubbing alcohol, apply a bonding primer (like Extreme Bond from Sherwin Williams), and then use the same topcoat as before.
