STAN DARD PROCEDU RE
STANDARD PROCEDURE - PLASTIC BODY
PANEL REPAIR
There a re ma ny different types of plastics u sed in
today’s aut omotive environment. We group plastics in
three different categories: Rigid, Semi-Rigid, and
Flexible. Any of t hese plastics may require the use of
an adh esion promoter for repair. These t ypes of plas-
tic are used ext ensively on Daim lerCh rysler Motors
vehicles. Always follow repair m ater ial m anufactur-
er’s plastic iden tification and repa ir procedur es.
Rigid Plastics:
Exa mples of rigid pla st ic u se: Fa scias, Hoods,
Doors, and oth er Body Pa nels, which inclu de SMC,
ABS, and P olyca rbonates.
Semi - Rigid Plastics:
Exa mples of semi-rigid plastic use: Interior Pa nels,
Under Hood Pan els, and other Body Trim P anels.
Flexible Plastics:
Exa mples of flexible plastic use: Fascias, Body
Moldin gs, and u pper a nd lower F ascia Covers.
Repair Procedure:
The repa ir procedu re for all three categories of
plastics is basically the sam e. Th e on e difference is
the ma terial used for the repair. The ma terials mu st
be specific for ea ch subst rate, rigid repa ir mat eria l
for rigid plast ic repa ir, sem i-rigid repa ir mat eria l for
semi-r igid plastic repa ir an d flexible repair material
for flexible plastic repa ir.

Adh esion Promoters/Sur face Modifier s are requir ed
for cert ain plastics. All three ca tegor ies m ay have
