I have some aluminum windshield trim that was painted black from the factory and the paint is wearing off. It looks like the same anodized aluminum used on cars with non-painted trim underneath.

What's my best strategy for repainting this stuff? Just sand and paint with semi gloss trim paint, or ...? Is there anything I can do to promote adhesion of the new paint to this surface? It doesn't look like the factory sanded it.

The correct color is called trim black Sems makes a good one. Just sand and use light coats.

Thanks Toms bird. I was kind of wondering if there was any chemical treatment I could use as an adhesion promoter, but sounds like all I need to do is a light sanding.

This looks like the stuff:

Painted trim failure was notorious on the trans am. I think most of it blew off as the car came left the lot! I sanded mine up to 220, then hit it with over the counter matte black appliance epoxy from a spray bomb. Car doesn't get as abused as it would have new, but the paint has held up great for the last few years. No wear at all. Some guys will powder coat them as well.

I have powder coated trim in the past and that's the best way AFAICT but this is a low-buck effort and I just want the best results for minimal $/time.

Thanks!

If you have the means to do it, black epoxy primer is the best product to start with for adhesion.

That's why I went with the epoxy appliance paint. Got it at Ace for prob $6 a can. I was going to powder coat but heard of some guys having fitment issues. Next set I do will be powder coated.
