How to make a lip kit for your ride. All you need is Carpet Tape and Garage door bottom seals or door seals are fine. I also put a little gorilla / krazy glue at the ends to stop it from peeling at the ends. For cutting I recommend getting some scissors.
This is a simple technique that costs about 50 dollars all the way around. each roll is about 10ft which is about 10$ and the tape is 10$ fiberglass carpet tape.
