When installing trim, some kits are permanent, and some can be taken off. If you need to remove a permanent installation, you’ll have to put on another kit after removing it. When installing a dash kit, you can choose between molded, and flat. Molded kits will fit the exact shape of your dash, but are more expensive. Usually seen on trucks and SUVs, molded kits have large rounded edges. Flat dash kits are flat, and when heated are flexible. The advantage of them is they’re cheap, thus normally seen on low priced automobiles. They have a wide color selection compared to their molded counter part, and have a lot more pieces per kit.
