Renew Protect Blak Once a Year. Then a coat of Renew Protect Glos after it dries. The Blak actually has carbon black in it. That's the same thing used when manufacturing tires that makes them black. I did mine back in early May at MOTD and they still look good. It's good for trim, tires, vinyl, and plastic.

 

C4 Gtechniq...for all the plastic trim.

If you don't like putting trim restorer on your car once a month this is for you. Lasts a year!

 

Thanks Vetsvette and GregoryK for your input.

 

I used this (when vehicle new)...



On all exterior rubber, plastic, trim. I did the plastic vents in front and rear bumper, the trim on the front and rear fenders, the plastic cowl (as you mentioned in your post) both visible and in the engine bay with the hood open, the mid cowl trim, the roof rubber trim, the tires (never armorall again) and rims.

Cheers
