I’m also going to cover the top of the plates plates with 3M PPF like I did on the front ones and then trim the excess edges with my wife’s craft razor exacto with a new blade....don’t tell her....
I finally installed these. I bent them slightly to fit the slight curve of the door sill. They have sharp edges so I cut two pieces of 3M PPF 11” x 4.5”. Traced and cut two more pieces the exact size as the door sill plates.
Installed the 11” x 4.5” PPF on the door sills. Installed the sill plates on top of the PPF. Covered the sill plates with PPF to protect them.
Sill plate installed:
PPF cut for top of the plate:
