Chemical Guys VRP.What products are you using? I used to use Mother back to black but that runs if there is a rain.
I've tried several products through the years and they all end up fading or not protecting as expected or staining even worse. All until I found the DuraCoating line up, that was final solution. From trim to fading pieces, restoring color, tire protection and shine. Best I've ever used so far and also on a quite reasonable price point, give it a try!What products are you using?

303 is the best I've used.If you have faded hard plastics or want to keep/slow them from fading, continuous application of 303 can help. I'm a big fan and use it on lots of stuff - boat vinyl, tires, RV decals.
However, I prefer to treat the ABS plastics and such with a restorative/protection product - Gtechniq C4 Permanent Trim Restorer. Expensive bugger, but worth it.
Use 303 on the flexible stuff.
