Decal Replacement

Flame Treating Decal Area

Plastic polyethylene material must be “flame treated" prior to
installing a decal to ensure good adhesion.  The flame treating
procedure can often be used to reduce or eliminate the whitish
stress marks that are sometimes left after a fender or cab is bent,
flexed, or damaged.

1.

Pass the flame of a propane torch back and forth quickly
over the area where the decal is to be applied until the
surface appears slightly glossy.  This should occur after
just a few seconds of flame treating.  Do not hold the torch
too close to the surface.  Keep the torch moving to prevent
damage.

2.

Apply the decal.
