White Alloy Body Filler is a two component unsaturated polyester body putty designed for automotive body repair, panel reshaping, and compatible industrial surface-repair applications.
During collision repair, dents, uneven surfaces, and minor contour defects may remain after metal panel straightening. Body filler helps restore surface contours and prepare the repaired area for subsequent sanding, priming, and refinishing.
This product features a fine white paste designed for smooth spreading, localized filling, and surface leveling. Its positioning emphasizes multi-substrate repair suitability, application feel, adhesion, and sanding convenience.
It may be considered for properly prepared and compatible steel, galvanized steel, aluminum, fiberglass, and selected sound existing paint surfaces. Actual substrate suitability depends on product specifications, surface preparation, and adhesion verification.
White color is a product appearance characteristic. It does not, by itself, establish higher adhesion, lower shrinkage, or better crack resistance than other body fillers.

White Alloy Body Filler is a polyester-based repair putty used to fill localized surface defects and restore panel contours before refinishing.
The product consists of a white main paste and a compatible curing agent. After mixing at the specified ratio, the material undergoes a curing reaction and forms a layer that can be sanded once sufficiently cured.
In automotive refinishing, body filler is typically used after the underlying panel has been straightened and prepared. It is not intended to replace professional metal straightening or to compensate for severe structural damage by applying excessively thick layers.
After curing and sanding, the repaired area normally requires suitable primer application before the color coat and clearcoat stages, according to the selected coating system.
Modern vehicle bodies may contain different metals and composite materials. The suitability of a body filler depends on both the product formulation and the substrate preparation procedure.
Steel panels are common substrates for automotive body repair. Remove rust, oil, dust, loose coating, and other contaminants before applying filler.
Complete necessary panel straightening first. The filler should be used for surface correction rather than as a substitute for repairing severely deformed metal.
Galvanized steel has a different surface condition from ordinary steel. Proper preparation is important for adhesion.
Use the surface-preparation procedure approved for the substrate and confirm that the specific filler is suitable for galvanized steel before application.
Aluminum requires attention to surface oxidation, contamination, and preparation. Do not assume that every polyester filler marketed as an alloy body filler is suitable for every aluminum alloy or surface treatment.
Confirm the manufacturer's substrate recommendations and perform adhesion testing where appropriate.
The product may be considered for selected fiberglass repair applications after compatibility is confirmed.
Remove surface contamination, including release agents where present, and prepare the surface according to the relevant repair procedure.
Application over existing paint should only be considered when the coating is sound, properly prepared, and compatible with the filler.
Do not apply over peeling, poorly bonded, contaminated, or otherwise unstable coatings.
Important: Multi-substrate positioning does not mean direct application is suitable for every metal, plastic, or existing coating.
Body filler is used to correct localized surface irregularities after appropriate substrate preparation and panel straightening.
White Alloy Body Filler is positioned for filling and leveling applications on compatible repair surfaces.
For deeper collision damage, carry out suitable metal straightening before filler application. Apply the material in controlled layers according to the product's approved thickness limits.
Excessively thick application can increase curing and sanding difficulties and may contribute to defects. The maximum permitted thickness must be confirmed from the official product data.
The product's fine white paste is intended to support spreading and contour adjustment during repair work.
Potential workflow benefits include:
The actual spreading feel and sanding performance depend on the formulation, mixing quality, hardener ratio, temperature, and curing conditions.
Not necessarily.
White paste may make the repair area easier to identify during application, particularly in workflows involving light-colored vehicles. However, the final paint color depends on the complete refinishing process, including primer shade, basecoat formulation, spray technique, and color verification.
White body filler does not guarantee a color match and does not replace appropriate primer selection.
White Alloy Body Filler uses a two-component curing system. The main paste must be mixed with the specified hardener at the approved ratio.
The supplied reference mixing ratio is 100:2 by weight.
At approximately 25°C, the supplied reference sanding time is 18–25 minutes. This is an indicative value and should not be treated as a guaranteed production specification until verified against the product TDS.
Adding more hardener than specified is not a reliable way to improve the product. An incorrect ratio may affect working time, curing behavior, surface quality, and subsequent coating performance.
Use the compatible hardener and follow the manufacturer's specified ratio.
Before sanding, check that the material has hardened sufficiently throughout the repair layer.
Potential signs of insufficient curing include:
A dry-feeling surface does not necessarily prove that a thick repair layer has cured completely.
The product is positioned around multi-substrate repair suitability, fine spreading, and sanding convenience. Actual differences from a general-purpose filler depend on the specific competing formulations and their test data.

White color alone does not establish a premium grade. Compare fillers using documented adhesion, sanding behavior, curing performance, and substrate compatibility rather than appearance alone.
Suitable for evaluating in localized bodywork repairs on compatible vehicle panels, including doors, hoods, fenders, and trunk lids.
The panel should be straightened as required before filler is used to refine its surface contour.
May be used in repair workflows involving white, pearl-white, silver, grey, and other light-colored vehicles.
Primer selection and final color matching must follow the complete refinishing system.
May be considered for compatible aluminum and galvanized-steel substrates after appropriate preparation and confirmation of suitability.
May be considered for localized surface correction on compatible equipment housings, metal cabinets, frames, and decorative metal components before suitable coating application.
Potential applications include selected fiberglass body panels, recreational-vehicle shells, equipment covers, and composite appearance parts, subject to product compatibility and correct preparation.
This product should not be assumed suitable for flexible PP or PE automotive components.
Ordinary automotive polyester body filler and specialized high-temperature conductive filler are not interchangeable by default.
Powder-coating processes commonly involve elevated-temperature curing. An ordinary automotive body filler may not withstand the actual part temperature and holding time, and it may not provide the electrical properties required by an electrostatic powder-coating process.
Potential problems with an unsuitable filler include:
White Alloy Body Filler should not be marketed as a high-temperature conductive powder-coating filler unless the specific product has been tested and approved for the intended process.
For powder-coating applications, select a dedicated filler with documented temperature resistance and electrical suitability for the actual curing cycle.
Remove oil, wax, dust, rust, loose paint, and other contaminants. Allow the surface to dry completely before proceeding.
Sand the substrate using a process appropriate to the material and repair system. The supplied guidance gives P80–P120 as a reference for conventional bodywork preparation, but substrate-specific requirements take priority.
For aluminum, galvanized steel, and fiberglass, follow the approved preparation procedure.
Whether the filler can be applied directly to bare metal or over a particular primer must be confirmed in the product TDS.
Check the condition of the main paste before use. Mix it according to the manufacturer's instructions if settling has occurred and the product remains suitable for use.
Do not use material showing abnormal hardening, severe skin formation, or persistent separation that cannot be corrected according to the instructions.
The supplied reference ratio is 100 parts main paste to 2 parts hardener by weight.
Use the compatible hardener and measure the components accurately. Do not substitute an unapproved curing agent.
Mix on a clean mixing board using a suitable spreader. Fold and press the material until the color and consistency are uniform, avoiding unnecessary air entrapment.
Do not return mixed filler to the original container.
Spread the material over the prepared repair area and build the contour gradually.
The supplied reference for a single layer is approximately 1–2mm. Confirm the product's maximum permitted thickness and use multiple layers where the approved process requires them.
The supplied reference sanding time is approximately 18–25 minutes at 25°C. Actual curing time depends on temperature, hardener dosage, layer thickness, and the product formulation.
The supplied reference sanding sequence is:
Adjust abrasive grades to the repair requirements and the primer system that follows.
Remove sanding dust and prepare the surface for the next coating stage.
A typical repair sequence may be:
Panel straightening → substrate preparation → body filler → sanding → compatible primer or primer surfacer → primer sanding → basecoat → clearcoat, where required.
Follow the approved product instructions for primer selection and recoating.
