GENERAL INFORMATION
Anti-rust treatment is necessary before welding and before and after the painting process.
ANTI-RUST TREATMENT BEFORE WELDING
Weld-Through Primer
(Spot Sealer)1. WELD-THROUGH PRIMER (SPOT SEALER)
APPLICATION
For anti-corrosion measures, always apply the
weld-through primer (spot sealer) to welding sur-
faces where the paint film has been removed.
HINT: Apply the weld-through primer (spot
sealer) to that it does not ooze out from the joining
surfaces.
WELD-THROUGH PRIMER (SPOT SEALER)
APPLICATION
ANTI-RUST TREATMENT BEFORE PAINTING PROCESS
Sealer Gun1. BODY SEALER APPLICATION
For water-proofing and anti-corrosion measures,
always apply the body sealer to the body panel
seams and hems of the doors, etc.
BODY SEALER APPLICATION
2. UNDERCOAT APPLICATION
To prevent corrosion and protect the body from
damage by flying stones, always apply sufficient
undercoat to the bottom surface of the under body
and inside of the wheel housings.

ANTI-RUST TREATMENT AFTER PAINTING PROCESS
1. ANTI-RUST AGENT (WAX) APPLICATION
To preserve impossible to paint areas from
corrosion, always apply sufficient anti-rust
agent (wax) to the inside of the hemming
areas of the doors and hoods, and around the
hinges, or the welded surfaces inside the
boxed cross-section structure of the side
member, body pillar, etc.
ANTI-RUST AGENT (WAX) APPLICATION
REFERENCE: ANTI-RUST TREATMENT BY PAINTING
Painting prevents corrosion and protects the sheet metal from damage. In this section, anti-chipping paint
only for anti-corrosion purpose is described.
1. ANTI-CHIPPING PAINT
To prevent corrosion and protect the body from damage by flying stones, etc., apply anti-chipping paint
to the rocker panel, wheel arch areas, valance panel, etc.
HINT:
Depending on the model or the application area, there are cases where the application of anti-chipping
paint is necessary before the second coat or after the top coat.

Apply the anti-chipping paint
before the second coat.
Apply the anti-chipping paint
after the top coat.

GENERAL INFORMATION
1. BASIC DIMENSIONS
(a) There are two types of dimensions in the diagram.
(Three-dimensional distance)

Straight-line distance between the centers of two
measuring points.
(Two-dimensional distance)

Horizontal distance in forward/rearward between
the centers of two measuring points.

The height from an imaginary standard line.
(b) In cases in which only one dimension is given, left
and right are symmetrical.
(c) The dimensions in the following drawing indicate
actual distance. Therefore, please use the dimen-
sions as a reference.
2. MEASURING
(a) Basically, all measurements are to be done with a
tracking gauge. For portions where it is not possible
to use a tracking gauge, a tape measure should be
used.
(b) Use only a tracking gauge that has no looseness in
the body, measuring plate, or pointers.
HINT:
1. The height of the left and right pointers must be equal.
2. Always calibrate the tracking gauge before measuring or
after adjusting the pointer height.
3. Take care not to drop the tracking gauge or otherwise
shock it.
4. Confirm that the pointers are securely in the holes.
(c) When using a tape measure, avoid twists and
bends in the tape.
(d) When tracking a diagonal measurement from the
front spring support inner hole to the suspension
member upper rear installation hole, measure
along the front spring support panel surface.
