Areas to protect include: the top and sides of the top tube, top and sides of down tube, fronts of forks, head tube, seat tube, chain stays and areas where cables rub on frame.

Part A - Prep and setup

1. Remove wheels, water bottle cages and loosen cables in the areas film is to be applied.
2. Identify all the areas of the frame that need to be covered with BONK! film and clean them with isopropyl alcohol and wipe them with a lint free cloth. You have to remove any dirt, grease or oil on the surface or the film will not adhere to those areas. Be careful not to ruin any existing decals with your cleaning solvents. We do not recommend applying film over rough weld joints.
3. Measure the areas for the film and create a paper template.
4. Now lay the templates on the BONK! paint protection film and trim out the perimeter (outer edge) of the pieces you need. When cutting out detail areas such as water bottle eyelets and unique contours or curves, first score the surface of the film with the blade. There is no need to cut all the way through the film, just cut all the way through at a tiny spot (enough to grab with a tweezer or your finger tips) once you have a hold of the film at the cut, just pull the film slowly and it will cleanly tear along your score line.
5. Now re-check all your pieces on the bike for proper fit before application begins.

Part B - Application

1. Wet your fingers and the area of the bike you plan to apply film to with the BONK! application fluid. Keeping your fingers wet during application will keep the films adhesive from picking up your fingerprints and unwanted dirt. Also put the squeegee sleeve on the squeegee and keep it wet too.
2. Pick your first larger piece and peel back a corner of the backing paper and spray the adhesive side with the BONK! application fluid so you can handle the film (are your fingers wet? And is the part of the bike this piece goes on wet?)
3. Now continue to remove the rest of the backing paper and wet the whole adhesive side of the film.
Lay the film on the desired part of the bike frame and slide it into proper position. Mist the outside of the film application fluid so the squeegee will slide across it without snagging the film. Take the squeegee and make a gentle pass down the middle of the material (long direction). do not use to much pressure when making this first pass or you may drag the film out of position. Then as the film begins to adhere to the bike frame, you can use more pressure and overlapping strokes until all the fluid and air bubbles are removed from underneath the film. Always work from the middle and center and move to the outer edges.
5. Once you finish this piece, make sure all the edges are down and tightly affixed. If an edge or corner doesn't lay down, re-spray the adhesive side of that area and re-squeegee the area down again and hold some pressure on the area for 10 to 20 seconds until the film adheres to the paint. If the film just will not adhere to the paint it is a good sign that the surface was not completely clean of grease or oil.
6. Now it's time to move to the next piece of film to be applied and repeat the same steps. It is suggested to start with the larger pieces and move to the smaller ones. Some of the tiny pieces of film if handled carefully can be applied without application fluid, just be sure not to touch the adhesive.

Make sure bike is up to 72 degrees Fahrenheit or warmer. Peel the film back 180 degrees along the bike frame. The paint protection film may peel off poor quality decals and paint. Be very careful during removal. The use of a hair dryer on low heat can soften the film and may make removal easier.

  • Most small bubble and wrinkles will disappear in a few hours or days
  • We do not advise applying film over rough weld joints
  • You can use a hair dryer on low heat to help make sure lifting areas stay down
  • The film will need a few hours for the adhesive to fully cure
  • BONK! paint protection film is sensitive to some chemical degreasers so always wipe the bike dry after any contact with chemicals

  "We are a custom mountain bike shop, and there are very few custom build bikes that I don't factor in BONK paint protection film into the base price of the bike. It has saved many paint jobs from harsh rocks and stones out there in the desert."
