Review: Custom fit on 2004 Honda Accord - 2hrs or less! - Product is a quality plastic that is very durable. I had to cut into the middle fin in order to fit this around my fuel tank's hitch(?). I have a 2004 Honda Accord EX sedan and had to cut down the stock bumper lip for proper fitment. This product looks great and took all of a 2 hours to install because I was triple checking my measurements. I didn't use the 3M adhesive supplied because I was able to use the bolt holes that the original bumper uses to bolt to the frame. This is currently held in by two 9mm plugs that are extremely secure. Overall, this product will most likely require custom fitment but is capable of being manipulated while keeping its durability!
Review: Great. - Great.
