I have not.
To date - I think the best solution to keep exterior pebble textured black plastic looking new, which means looking black and not showing Zebra Stripes with age is to start ASAP with a dye like Solution Finish and then repeatedly apply this product as preventative maintenance.
For any car that has this type of plastic, and is exposed to the sun, then there is no such thing is as,
One and done - OR -
Set it and forget it.
The best thing you can do is find a product that works and use it often.
And just to note, after using a product like Solution Finish, you still need to apply a topper to seal the surface and protect it. Solution Finish is only a dye - it's not a dressing or a protectant or a coating.
We recently purchased a new vehicle and the first thing I did was treat the brand new plastic - that looked great - with Solution Finish. Luckily for us, most of the time, this vehicle is parked undercover, out of the sun.
After treating with the Solution Finish - next we applied our new Trim Coating Pro to seal the plastic. That said - I plan to re-apply both products at least twice a year - again - as PREVENTITIVE MAINTENANCE.
Here's a video sharing some info about this type of plastic.
