I really like this thing. I personally have not used this for an auto grill. I wanted something that would match the doors of my sideboards that I bought for the house. They came with doors that were the exact same wire design and I added matching wall cabinets. I cut out a door insert for the upper cabinets and used it. They are perfect for the look I wanted. This is not a high density material. I just cut it to the right length with scissors and it attaches easily to the doors. lol probably not what you guys want with cars but this lady is one happy camper!
