VSM V1080S High Performance Primer Surfacer is a professional two-component automotive refinishing primer designed to level repaired surfaces before topcoat application. Used with VSM V1025H Primer Hardener, it provides high filling performance, easy sanding and a dense intermediate barrier between the repaired substrate and the automotive topcoat.

This 2K acrylic polyurethane primer surfacer is suitable for sanded steel, existing paint films, cured epoxy primer and polyester body filler surfaces. It is particularly useful after putty repair, feather-edge sanding, localized collision repair and full vehicle repainting.

The product is mixed at 4:1:2 by weight or 4:1:3 by volume with compatible thinner. After proper curing, the coating can be wet sanded with P800–P1000 abrasive paper to create a smooth, uniform foundation for basecoat and clearcoat application.

After body filler shaping, repaired panels may retain fine pinholes, sanding marks and small surface irregularities. V1080S is designed to build and level these defects, creating a more uniform surface before color application.

The cured 2K film forms a dense barrier that helps isolate the repaired area from the stronger solvents used in subsequent topcoat layers. This is especially important when refinishing old paint films and feathered repair edges.

A properly cured V1080S film is designed to sand dry and produce fine sanding dust rather than clogging the abrasive. This can help reduce sandpaper consumption and improve technician efficiency.

The coating is designed to establish physical anchoring on properly sanded steel, cured epoxy primer, old paint film and body filler. A stable primer surface supports more reliable adhesion of the next coating layer.

The product can be used for local repair zones, putty repair areas, old-paint refurbishment and full-body preparation before automotive topcoat application.

After polyester body filler has been shaped and sanded, apply V1080S to fill fine pores, sanding marks and minor imperfections before the color coat process.

For repaired doors, fenders, bumpers and quarter panels, use the primer surfacer to create a smooth transition between the repair zone and the surrounding old paint film.

After sanding stable existing paint, V1080S can provide a uniform intermediate foundation for vehicle repainting and refinishing work.

Use the product over sanded feather edges around repair zones to help reduce edge swelling, lifting or solvent sensitivity under later coating layers.

After preparing a complete vehicle surface, V1080S can be applied to establish a consistent, sandable primer layer before basecoat application.

V1080S can be applied over:

• Steel sanded with P400–P600
• Stable old paint films sanded with P400–P600
• Fully cured epoxy primer
• Properly sanded polyester body filler

Remove dust, grease, moisture and loose coatings before spraying.

Do not apply directly to stainless steel or galvanized steel.

Mix V1080S, V1025H hardener and compatible thinner accurately. Stir until uniform and filter before use.

Apply two even coats. At approximately 25°C, allow 5–15 minutes flash-off between coats.

Avoid excessive wet film build in a single pass, especially around repair edges.

After the primer film is fully dry, wet sand using P800–P1000 abrasive paper before topcoat application.

Check for remaining pinholes, scratches or repair-edge irregularities before applying basecoat.

After sanding and cleaning, apply the selected compatible automotive basecoat, followed by clearcoat where required by the paint system.

1. What is VSM V1080S used for?

V1080S is a 2K automotive primer surfacer used to fill sanding marks, level body filler repairs, isolate repaired surfaces and provide a sandable base before automotive topcoat application.

2. What is the mixing ratio for V1080S?

The recommended mixing ratio is 4:1:2 by weight or 4:1:3 by volume for primer, V1025H hardener and compatible thinner.

3. Can V1080S be applied over body filler?

Yes. It is suitable for properly sanded polyester body filler and is designed to help fill small pores and sanding marks.

4. Can this primer be used over old paint?

Yes, provided the old paint film is stable, clean and sanded with P400–P600 abrasive paper.

5. Can I spray V1080S directly on stainless steel or galvanized steel?

No. It should not be applied directly to stainless steel or galvanized steel. Use an appropriate substrate preparation and primer system first.

6. What spray gun setup is recommended?

Use a gravity-feed spray gun with a 1.5–1.7 mm nozzle and 1.8–2.5 bar spray pressure.

7. How many coats should be applied?

Apply two coats, allowing 5–15 minutes of flash-off between coats at approximately 25°C.

8. What grit should be used before topcoat application?

After the primer has dried fully, wet sand with P800–P1000 abrasive paper before applying the automotive topcoat.
