Door vinyl chrome trim strip from Zcar Depot

Has anybody tried these?  Are they any different from the generic moulded-vinyl stick-on strips available at parts stores?  Since the original accent strip is heat-embossed to the door card vinyl and thus not removable, I'm having difficulty visualizing how that kind of stick-on strip (has a flat mounting surface) can be installed on top of the original strip without it sitting way too high.  I'm hoping that these might, instead, have a 'U' cross-section so that they fit as a cap over the original strip.
