I drive a Demon (and not the other way around)

A question was put to me. "How do I find where all the holes are in the floorboards?" first, the floor needs to be free of the seats, and floor covering that includes all carpeting and floor mats. I put covers in every drain hole in the floorboards and put a bolt in every seat belt hole. That leaves the 4 seat mount holes (bench seat cars only, bucket seat vehicles have 8) that are accounted for. I take two flashlights, one I put a photo diffuser on it, place it under the car, the other is used as a dark garage navigation aid. Turn on the second flashlight, turn out the light in the garage, then get in the car. Once safely inside, turn off the second flashlight. Give your eyes about 20-30 seconds to have your "Night vision" become fully functional. In the event I missed a factory intended hole, I always take roll of blue masking tape inside the car with me. When one of the offending holes is found, I put a small piece of tape over the hole(a chalk mark or a bright colored grease pencil will do), until there is no more light visible coming into the passenger compartment from the flashlight underneath the car. It is better practice to move the flashlight under the car to the floorboard of each seating position so that the brightest rays will be more readily identified. I was very glad I did this. I found 2 previously undetected pin holes, that I will need to address with a structural adhesive such as the two-part JB Weld. I don't recommend using flex-seal or like product because it won't produce as strong of a bond and it isn't flame retardant. Once you use either product, you are at least two days away from applying anything over top of it.
You will need to use the flashlight you brought in the car as a light to make your way back to the light switch in the garage. I don't want to hear of anyone who has heard a bump in the night and awoke to figure out it was them.
