54 0 ... Repair Instructions For Bonded Seals
1.General information on handling rubber seal profiles:
-
If seals reveal partly detached protective film on delivery, they must not be bonded.
-
Store seals at 15 °C to 25 °C.
-
If, during the handling, the protective film has come off before bonding, it can still be bonded.
-
Bonding at room and object temperature >20 °C. Temperatures between 40 and 50 °C significantly increase initial adhesion.
-
Seals, which are subjected to temperatures above 80 °C after gluing, will be very difficult to remove.
2.Damage pattern and repair
2.1 Partially detached bond (rubber-adhesive tape or adhesive tape-paint)
-
Up to 120 mm for retouching without auxiliary resources
-
Up to 200 mm repaired with pressing-on tools on straight surfaces
a
Cleaning damaged areas:
-
Degrease bonded area with adhesive cleaner (refer to BMW Parts Service) and remove other residues.
NOTE:
-
Use necessary cotton-or fluff-free paper towel once only.
-
When using solvent:
expose repair area to air for at least 2 minutes.
b

Do not apply adhesive to visible painted surfaces.
c
Pressing on rubber seal:
-
Press down seal using contact pressure (forced pressure not necessary) for at least 1 minute.
CAUTION: Load can only be applied to the bond after a period of 2 minutes. This waiting time is absolutely essential.
2.2 Larger defects (mechanical damage and larger separations of seal)
-
Complete replacement of rubber seal necessary
a
Peeling off damaged rubber seal:
-
Pull off rubber seal slowly at an angle up to 20° under uniformly strong tension.
NOTE:
-
Make sure the connection between adhesive tape and seal is retained.
-
If the connection between adhesive tape and seal is detached: Carefully and slowly detach adhesive tape at an angle of 20° from roof
opening or lid.
-
When existing seals are being peeled off with a hot air blower: Do not damage paintwork.
-
Do not detach rubber-adhesive tape connection if at all possible.

NOTE:
-
Use necessary cotton-or fluff-free paper towel once only.
-
When using solvent:
expose repair area to air for at least 2 minutes.
c
Detaching protective film from bonded area:
-
Detach protective film from rubber seal in sections.
