Looks good! What did you use to clean them?

 

Just water and dish soap.

I was afraid to take them off in case I broke the little tabs doing it. Cause they seemed brittle

 

I did look reach my hand up under the bed rail and noticed the same thing about the tabs. Im kinda nervous that once I pop the rails off the cap wont snap back in to place and I will have to buy a new one and just wasted time painting the old ones.

The rear tailgate piece is very simple as well. There is a 6" wide plate that runs the length of the tailgate, held on with a dozen or so star bolts. Just take a screw gut to them and in no time the piece will be off. Ive been through 3 of the tailgate trim.
