Good solution.

The Mopar accessory pad isn't ideal for our Gen2 as the shape is not correct for the outlined area as your image shows, and it overlaps at the ends .. very minor, about 1/8". It is discontinued from Mopar but a few accessory shops still have them.

The top of that bumper gets as much sun and UV as the hood and roof but being plastic, it does not dissipate heat as well as metal so the paint deteriorates. Mine had delaminating clear coat and some nicks from cargo so I bought the pad to cover it. I like the looks of yours better.

 

The roof, both 1/4 panels and rear bumper are the only original 19 year old paint, everything else has been repainted at one time or another, some areas several times.

I have always had covered parking where I have lived, so the car has had that protection.

 

I knew a guy who worked for Linex. He had a 3" strip of Linex run on the side bottoms - rocker panels, doors and fenders. It looked good and hopefully prevented the rust from appearing over the rear fender wells - common on every brand of pick up.

I noticed my neighbor's Ram had rust in the rocker panels. His truck is the generation as my '15 is.

 

You application looks better than the factory pad. It's like whoever made the factory pad never saw the bumper it was supposed to be used on since the shapes don't match.

 

The pad looks fine on a Gen1 because the bumper is smooth, but then they never designed a new pad to properly fit the Gen2, but just carried over the one style.

When they designed in the molded pad area on the Gen2, they could have done, at the factory, a treatment similar to what I had done and it would have cost about $10/vehicle.

But the molded pad area is also what made it so easy for the shop to do it as all they had to do was to mask around the line. It was probably about $20 in Rhino Lining material and the rest was labor, but I'm happy with the results.

 

Replaced the rusted-out rockers on my PT several years ago. Used clecos to hold them in place and riveted them on (only have a stick welder here). Painted them with bedliner and it completely covered and concealed the rivet heads. Has held up well thru several Michigan winters.

 

Nice, creative repair. Looks good!
