Solid Colour
To the matched colour, add Flexible Additive then Hardener and Reducer in the following ratios:
426 line colour - 5 parts by volume
Flexible Additive 499-35484 - one part by volume
2K MS Hardener 980-35239 - three parts by volume
2K Reducer 920-19148 - 10-20% by volume
Stir thoroughly and strain. Put on the air s upplied respirator. Using a 1.4 - 1.8 m m fluid nozzle on a standard spr ay
gun, apply one medium wet coat. Apply a further one or two coats to achieve coverage allowing a 3 - 5 minutes
flash-off time between coats. If low baking, this can be done immediately (no more than five minutes flash-off) at
60°C for 40 minutes. If air drying, allow 16 hours to dry (correct film thickness is 40 - 50 microns).
Cobra Basecoat, Metallic, Pearl or Solid Colour
Thin the matched basecoat colour with Cobra Basebuilder, 920 line at a 1:1 mix ratio and stir thoroughly, strain
material, and using a 1.4 - 1.6 mm gravity feed spray gun, apply one medium wet even coat. Allow to flash off f or
5 minutes before applying the next coat.
Apply one or two further coats to achieve a uniform and even coverage with five minutes flash-off between coats.
Allow 10 - 20 minutes drying before applying clearcoat.
Mix 2K Clearcoat with Flexible Additive then Hardener and Reducer in the following ratios:
-2K Clearcoat 455-30900 - five parts by volume
-Flexible Additive 499-35484 - one part by volume
-2K MS Hardener 980-35239 - three parts by volume
-2K Reducer 920-19148 - 20% by volume
Stir thoroughly and strain. Put on the air supplied respirator. Using a 1.4 - 1.8 mm fluid nozzle spray gun set-up,
apply one medium wet coat to the basecoat (after allowing the Basecoat 10 - 20 minutes drying time). Apply a
further one or two wet coats after a 3 - 5 minutes flash-off between coats. If low baking, this can be done
immediately after the last c oat but do not allow mor e than 5 m inutes flas h-off . Bak e at 60°C for 40 m inutes or, if air
drying, allow 16 hours.
REPAIRING COLOUR COAT
Superficial damage to the paint film and/or plastic surfaces may be rectified by sanding and repainting. Parts having
deep gouges in the plastic surface should be replaced because repair methods using filling materials and thinning
down of the plastic section may reduce overall impact strength.
For shallow paint damage, follow the procedure listed under “Colour finishing of replacement parts”, using P800
paper to sand down imperfections and using an abrasive pad or P1200 paper, scuff and key existing paintwork.
Basecoat and Clearcoat can be spot repaired by blending away the basecoat colour but spraying the complete
bumper with Clearcoat coats. Solid colours are best sprayed as complete panels. If the damage extends to the
plastic surface, this must be primed with Plastpak Universal primer after the correct cleaning procedure.
CAUTION: Drying of all products may be accelerated by heat, but to avoid distortion, unsupported bumpers
should not be heated in an oven or by lamp above 60°
