STI Roof Spoiler – 2025 Subaru Forester

SEOCONTENT-START

1. Be sure to observe the content in CAUTION for installation described in the main text during the work.
Neglecting it may cause dropping of or peeling-off on the part, and also may prevent the vehicle from functioning.
2. Before the installation, turn the ignition switch to OFF, and apply the parking brake without fail.
3. Do not use thinner or the like, otherwise the surface of the STI ROOF SPOILER may be corroded. Also, keep the spoiler away from fire, otherwise it may be deformed.
4. When the ambient temperature is 15°C or lower, warm up all strips of the double-sided tape and around the installation portion of the STI ROOF SPOILER to approximately 25 to 40°C using a dryer or infrared lamp.
Local warming may deform the part. Do not use an industrial dryer.
5. Firmly press the double-sided tape to adhere well.
If it is reattached, the adhesive performance will extremely decrease. To avoid redoing, position the tape correctly before attachment.
6. The adhesive strength of the double-sided tape increases gradually after the attachment. Do not wash the vehicle within 24 hours after attaching the part.
When washing the vehicle or applying wax to the vehicle is required on the day when the part is attached, leave the vehicle for at least 1 hour, and seal the double-sided tape attached portions with tape or the like to prevent water intrusion.
In addition, be careful not to apply an excessive force to the STI ROOF SPOILER.
(Do not perform a high-pressure or automatic car wash on the day when the part is installed.)
7. When performing an air blow after the installation of the part, keep the nozzle 300 mm or more away from the part. If it is too close, the surface of the part may be peeled off.
8. Perform degreasing so as not to allow any solvent to accumulate in a gap of a component. A liquid pool may adversely affect the coated surfaces, rubber materials, and the like. Use a soft waste cloth to absorb the solvent and wipe the necessary portion. Then, wipe off completely with a dry waste cloth.
9. When a body coating treatment (glass coating, etc.) is applied, the original adhesive strength cannot be exerted. Check if the body coating treatment is applied. Also, remove any dirt or fat and oil without fail, and apply a firm pressure sufficiently.
<>
• Using compound with fine particles (in order not to impair painting), scrub off the coating film in the application area.
• After grinding, spray water using a spray or the like. If the area is no longer water-repellent, the coating film is removed.
