I teach Plastics and can only suggest things. Chrome has a radically different expansion rate than plastic. In most chrome on plastic items the chrome is really a series of small flakes like dried mud in a shallow puddle. Each crack is enlarged and the under lying attachment is further sheared when it is heated or cooled (think early Mazda badge emblems on trunks). The darker truck looks like it was heated to near melting at one point. The chrome issue also follows the same pattern from the front left corner to the rear becoming less and less severe toward the back. Sunlight can and will also cause plastic to degrade and decompose. If the chrome in the noy quite destroyed zone is flaky and near powder, I suspect heat, Sun, or a chemical like furniture polish/spray. Remember the cracks and flaking are pretty small and happen when plated. Chemicals can get into the cracks and under the flakes. Jim
