PIPER CHEROKEE SIX SERVICE MANUAL
g. Painting the Repair:
1.
An important factor in obtaining a quality paint finish is the proper preparation of the repair
and surrounding area before applying any paint.
2.
It is recommended that parts be cleaned prior to painting with a commercial cleaner or a
solution made from one-fourth cup of detergent mixed with one gallon of water.
3.
The paint used for coating thermoplastic can be either lacquers or enamels depending on which
is preferred by the repair facility or customer. (See NOTE.)
- NOTE-
It is extremely important that solvent formulations be considered
when selecting a paint, because not all lacquers or enamels can be
used satisfactorily on thermoplastics. Some solvents used in the
paints can significantly affect and degrade the plastic properties.
4.
Another important matter to consider is that hard, brittle coatings that are usually best for
abrasion resistance should not be used in areas whick incur high stress, flexing or impact. Such coating may
crack, thus creating a weak area.
