Tried that didn't work.

 

Look at this thread. Not VDP but the rough country end caps bedlined.

Guys on jetski forums have actually had luck using a heat gun to heat up the plastic just a little bit then dunking the part in water, not sure if it will work on the plastic used on the bumper of the JKs

You could also try using Turtle Wax Ice wax it does a pretty good job making black plastic look nice and dark IMO.

 

Maybe a SOS pad or 2000 grit sandpaper will dull it up. I have RC end caps and they look a little newer then the rest of the bumper but I live with it and over time it will fade!!!

 

Here is a pic of my bumper

 

I was gonna use krylon fusion but ended up using bedliner

 

then rhino it....or replace !!

 

I just recently painted my bumpers and running boards. They looked really bad and I had to do something about it. I took everything off because I don't trust myself enough with spray paint around the jeep but it came out really good when I got it all back on. I just used Krylon Fusion Satin spray paint from Home Depot for like $20. I got before and after pictures if anyone whats to see.

 

Nice rig man!

What brand/model of tire are you running and what size are they? Nice looking!

 

I did the RRC kit before I changed bumpers. Took everything one step further since I was bored and put a bead of black silicone around the gap between the caps and the bumper itself, then bedlined the whole thing. Not necesary by any means but it cleaned the look up a lot.
