Best coating for hard black plastic

[Crispy]

Have researched for best product to coat black plastic.

Plan on coating some grill inserts for my 2001 grand prix.

They are all cleaned and lots of honey comb cells to treat.

I have :

GTechniq Trim Sealant
Optimum Gloss Coat
Opti-seal
Many pollymer and spray on waxes.

I'm thinking a spray would be easiest buy looking for suggestions.

Plasti Dip.

You may want to look at CarPro CQuartz DLUX.
Regardless of product, some skill will be involved when working with honey-comb grill unless you can airbrush the coating in.

I have no experience with it, just what I've read and seen around.

But, I think the best option, if they are in good condition, would be to "spray on" a coat of Gloss Coat if you could.

Next, maybe that really durable spray on glossy coating that Meg's has. I can't remember which one it is, but if they are out of the vehicle, it may be a good option.

You could go the "find what you like and use it often" route with one of the spray waxes/sealants too if they look good.

I always liked Wax as U Dry Quik Wax on grills and front ends. It darkens some plastics a little and is nice to use.

Also you might look into the Ultima Trim Guard Plus.

But if it's just a regular painted surface, any of your sealants will work great.

Get an airbrush setup from Harbor Freight and spray whatever you use. Ive never sprayed Gloss Coat however. I usually spray Dlux. You can spray Opti Seal as well.

UTTG can be finicky on some surfaces, especially "hard" black plastics. Textured (~porous) trim is not so much of a problem. But it sometimes gets tacky for me on some substrates and becomes difficult to remove and/or wipe. If one does attempt it on those surfaces, it's important to wipe off the excess immediately. Otherwise it becomes a dust/lint clinging mess and finger print collector.

Superb on some things, the opposite on others.

What about one of those spray on sio2 products if you can't airbrush or use q tips?

McKee’s 37 Hydro Blue Sio2 Coating

Or

CarPro Hydro2 Touchless Silica Sealant 1 Liter

I've never used it, but have read people get about 3 months durability.

Paint them satin black less maintenance.
