The plastics of my project are getting gray because of the sun over years. I would like to restore them so they look brand new and solid black. I used a fine sandpaper to gently sand them to make the paint stick. I used a mast black paint spray can to paint them. The result looks good but not perfect. Is there a better / more common way to renew some exterior plastic trims on a car.

Let me know please !

Before you sanded the plastic pieces, you most likely could have just used a plastic conditioner to bring back the shine.

But since you sanded it, I'd end up painting it with the best satin paint you can find. If I'm forced to use spray paint, I often use engine enamel paint, as the durability and quality, I feel, is far superior.



Contrary to popular belief. Don't use armor all, it actually dries most materials out, causing more damage than good. Don't be fooled by the shine.

how about using plasti dip ? I've been thinking about doing that

buy new pieces

This. Plastics are cheap.



I haven't had problems with meguiar's on the hard plastics. I don't use it on seals or vinyl though.
