Decal Application


Non-Oil Based Surface Cleaner

Spray Bottle filled with Clean Water

Clean Lint-free Rag

Semi-Hard Plastic Edged Tool (squeegee) or Credit Card

Pencil or Marking Tool


  • Ensure that the surface on which the decals will be applied to is completely clean and free of oils, grease, debris, cleaner, or any other contaminants. 
  • The best location for applying your Diver-ID decals is typically about an inch or so above the tank boot (plastic base) and well below your tank strap or between the straps if your BCD has dual tank straps. Gear technicians will need to remove the tank boot for visual inspection annually and buckles can scrape your Diver-ID. 
  • Savvy installers first put the BCD on the tank, note where the tank strap sits on the tank before taking the BCD off and mark lightly where the edges of the decal should sit on the tank before carefully applying their Diver-ID decals.
  • Most divers apply their Diver-ID decals horizontally on the rear of the tank (opposite valve opening) with Single tanks. On Doubles they are sometimes applied vertically.
  • Applying a small amount of clean water with a sponge, cloth, or spray bottle to the surface of the tank before decal application will not harm the adhesive of your newly purchased Diver-ID.COM decals and will allow you to slide or adjust them a bit to properly position them to your liking. The wet surface also helps to remove air bubbles when you press or smooth out any remaining water from under the decals.
  • Smooth or press out any bubbles with a credit card or semi-hard plastic edged tool. 
  • Once any remaining water that you've applied dries completely, the adhesive will stick to the surface just as well as if no water had been used at all during the install.


Decal Removal


Hair Dryer or Heat Gun

WD40™ or GOO GONE™

Wide Roll (3" or more) Masking Tape

Semi-Hard Plastic Edged Tool (squeegee) or Credit Card


  • Heat decal to be removed with hair dryer or heat gun to soften the adhesive of the decal, being very careful not to burn oneself or melt the decal. Too much heat can make quite the mess and possiblly result in harming the remover. Tank will get hot.
  • While the decal and tank are heated, begin peeling up a corner of the affixed decal.
  • Carefully and slowly pull the corner edge of the decal away from the tank while hot.
  • Some 3M™ Reflective film and its decal adhesive will likely remain after you have removed the majority of the decal. Diver-ID.COM decals are designed to be very durable and stick fast in harsh marine environments. Do not expect the decals to come off easily and without significant effort on your part.
  • Lay a wide length of masking tape completely over the remaining decal film and adhesive and press it flat with the squeegee or credit card.
  • Heat the masking tape and contents underneath, pressing it flat with the edged tool to allow the masking tape to fully adhere to the remaining film and decal adhesive.
  • Rapidly pull the masking tape back at an angle to remove both the masking tape and the remaining film and decal adhesive in one fell swoop. This should remove the majority of the decal's remaining film or adhesive.
  • WD40™ or GOO GONE™ can be used to remove any remaining traces of the decal.
