Why Choose White Alloy Body Filler?
Fine White Paste for Controlled Application
The fine paste consistency supports smooth spreading and localized surface correction. Technicians can shape the repaired area before sanding to help achieve a more uniform surface.
Efficient Filling and Leveling
Designed for filling small dents, surface irregularities, and repaired panel areas after appropriate substrate preparation. It supports the body repair process before primer application.
Practical Sanding Performance
After curing under suitable conditions, the material can be sanded to refine the surface profile. Actual sanding time depends on temperature, hardener dosage, layer thickness, and substrate conditions.
Multi-Substrate Repair Potential
The product may be suitable for selected metal and fiberglass substrates. Confirm the manufacturer's technical data and perform a compatibility test before use on aluminum, galvanized steel, fiberglass, or existing coatings.
A Practical Option for Professional Repair Supply
For distributors and automotive refinishing suppliers, this product can be positioned as a white polyester filler for routine panel repair and compatible surface-leveling work. Confirm available package sizes, order quantities, and private-label options before placing an order.

Typical Applications
Automotive Body Repair
- Localized dents on doors, fenders, and quarter panels
- Surface leveling after metal panel straightening
- Contour correction on repaired body panels
- Preparation before compatible primer and refinishing paint
Metal Surface Repair
- Selected steel components
- Properly prepared galvanized metal
- Aluminum components where adhesion and compatibility are confirmed
- Selected industrial metal parts requiring surface filling
Fiberglass and Composite Repair
May be considered for compatible fiberglass components after checking the substrate condition and the manufacturer's application instructions.
Not recommended without verification: Flexible plastics such as PP and PE, unstable old coatings, contaminated surfaces, or applications exposed to high-temperature powder-coating ovens.
Application Process
Step 1 — Inspect and Prepare the Surface
Remove rust, loose paint, dust, oil, and other contaminants. Straighten damaged panels as needed. Use a suitable abrasive, such as P80–P120, as a reference for preparation, subject to the substrate and product instructions.
Step 2 — Confirm Substrate Compatibility
Check whether the prepared surface is suitable for polyester filler. Follow the product TDS for bare metal, galvanized steel, aluminum, fiberglass, and existing coatings. Do not assume the filler is compatible with every substrate or primer.
Step 3 — Mix with the Compatible Hardener
Use the hardener specified for the product. A mixing ratio of 100:2 by weight is provided as a reference. Measure accurately and mix thoroughly until the material is uniform. Avoid excessive hardener or incomplete mixing.
Step 4 — Apply and Shape
Spread the filler evenly over the repair area. The reference single-layer thickness is approximately 1–2 mm. Avoid excessive build in one application and follow the manufacturer's maximum thickness requirements.
Step 5 — Allow to Cure
The reference sanding time is 18–25 minutes at 25°C. Actual curing varies with temperature, hardener dosage, film thickness, and working conditions. Confirm the material is adequately cured before sanding.
Step 6 — Sand and Refine
Use suitable abrasives to shape the filler and smooth the repair. A reference sequence is P120/P180 followed by P240/P320, adjusted to the repair and the next coating system.
Step 7 — Apply the Compatible Coating System
Remove sanding dust and apply a compatible primer or primer surfacer. Continue with primer sanding, basecoat, and clearcoat where required by the selected refinishing system.
