PSU mod med UV-Reaktivt "Contractors tape/ Flagging tape." Loom og krympeflex eller spiral flex er normalt det man ser brugt i PSU mod, men denne guide har de opnået et flot resultat ved brug af UV-Reaktivt "Contractors tape/ Flagging tape."
Now you can get a product called Contractors tape or Flagging tape from most local hardware stores in many UV colors. I paid $1.99 for mine at Home Depot. http://creativemods.com/guides/psumod.php
