Application Instructions

On a properly sanded old surface (P500 grit)

Step 1 : Apply the white basecoat

Mixture: ready to use (already diluted)

Apply several fine coats, with 2–5 minutes between coats

Overcoat with OPAL within 30 minutes.

Step 2 : Apply the OPAL effect coat

Mixture: 100 parts stirred OPAL paint + 50–100 parts thinner

Apply 3 to 5 fine coats, at intervals of 2–5 minutes

Overcoat with clearcoat within 30 minutes.

Step 3 : Apply the clearcoat (3:1 ratio)

Mixture: 100 parts clearcoat + 33 parts hardener + 5–15% thinner (Pot life: 45 minutes)

Apply two full glossy coats with a 10-minute flash-off between coats.

Note :

► The three stages should ideally be applied successively to allow wet-on-wet adhesion. However, if necessary, a full drying period followed by sanding with a grey abrasive pad is possible before proceeding to the next stage.

► The OPAL paint can be applied over any professional-grade white background except waterborne basecoats:

• Old glossy opaque white paint (no pearlescent paint)

• White primer

Difference Between Classic OPAL and Quasar OPAL

Classic OPALs use very fine synthetic mica particles, offering subtle reflections. These are more affordable shades.

Quasar OPALs have a unique composition based on transparent metals, producing more intense colour reflections and more dramatic colour shifts.

Visual Appearance

Stardust's special OPAL effect is a transparent pearlescent paint containing ultra-fine particles (10–40µm or 10–60µm) that reflect light and create a shimmering effect.

Depending on the angle of view, an OPAL paint can reveal two to four different colours.

Secondary colours are most visible between 0° and 30° viewing angles.

Gloss, Satin, or Matt Finish

We recommend applying a glossy clearcoat to optimise light reflection and enhance the visibility of the OPAL pearlescent effect.

A matt clearcoat is not recommended, as it significantly diminishes the light reflection and the visual impact of the pearlescence.

However, it is possible to use a satin clearcoat with 20° gloss, which can be included in the kit as a replacement for the standard gloss clearcoat.
