factory finished if acceptable to topcoat manufacturers.

B. Tint each undercoat a lighter shade to facilitate identification of each coat if multiple coats of

same material are to be applied. Tint undercoats to match color of topcoat, but provide sufficient

difference in shade of undercoats to distinguish each separate coat.

C. If undercoats or other conditions show through topcoat, apply additional coats until cured film

has a uniform paint finish, color, and appearance.

D. Apply paints to produce surface films without cloudiness, spotting, holidays, laps, brush marks,

roller tracking, runs, sags, ropiness, or other surface imperfections. Cut in sharp lines and color

breaks.
