What product to clean plastic grille on 83 Volkswagen?

[detail1]

The grille is in good shape but needs a little freshening up. What can I use to spice it up and get rid of the dullness. It does not need paint.

Thanks

I use 303 on my 02 VW grill and that keeps it looking great. It soaks in and both removes hazing and darkens it to a nice satin black. At first it wore off fairly quickly, but after repeated applications over time, whether it needed it or not, it seems to penetrate and stay there for a long time.

Same thing for all the rubber window trim.

On grilles like that I always try KAIO first. I've also done OK with VM and (on my '87 VW Quantum) Pinnacle PCL.

But these days I'd use the KAIO. For that matter, I'd seal it up with KSG too, though I've also used other sealants with good results.

No dressings on exterior plastic for me, unless all my various LSP-based approaches fail, and that doesn't happen very often.
