Yes, I used a cheap pencil style 30 watt soldering iron because the good trigger style solder irons were out of stock. I made sure the carpet layed out in the sun for a while before placing the carpet in my car. I used the OCD method to make sure the carpet was perfectly set before cutting any holes. I carefuly lifted the carpet from inside the car to check for the seat holes ETC. Then I marked the locations with pieces of blue painters tape. Then I poked a screwdriver through each tape area to verify that it was properly aligned with the hole. Then I placed the hot solder iron on each location. I did not want to crawl under the car to do this which some members may prefer. However, the gas pedal holes were difficult to mark from inside the car so I hit the solder iron from underneath. The gas pedal studs are not long enough to penetrate the thick carpet to install the nuts from underneath therfore, I had to make a small slice in the carpet and insert the pedal mounting bracket under the carpet pad. My holes were right on the money the only trouble I had was with the seat belt bolts because my holes did not allow the larger diameter bolt to penetrate the heavy vinyl backing on the premium carpet that I ordered. Therefore, I had to enlarge those holes with a razor utility knife.
