Good advice there from JD.....I have tried most things on my black trim. Aerospce protectant is EXCELLENT, but is costly (I use it now only when I re-wax the car after stripping it). Recently I have been using Poorboys natural look dressing. I love this stuff! You can use it on your interior, outer trim, engine plastics and even the walls of the tyres! It lasts ok and is very easy in its application. The price is very affordable too! Apply it with a microfibre pad or sponge applicator, leave it if you want a shinyer look, or buff it off if you want a duller but natural look. AMAZING STUFF!
