2K CHPO Polyester Putty for Automotive Body Repair, Metal Filling, Leveling and Surface Shaping
Bright Economy CHPO Polyester Body Filler is a two-component polyester body filler designed for conventional automotive body repair and general filling applications.
It uses a CHPO curing system with yellow hardener and is primarily positioned for steel sheet, iron and conventional metal substrates where the main requirements are filling, leveling, shaping and sanding.
Unlike BPO multi-purpose fillers designed for broader substrate compatibility, Bright focuses on a simpler and more economical repair requirement:
For conventional steel repair, use a practical filler for the work that occurs every day.
Automotive body repair often involves restoring a damaged panel after dent pulling, welding or sheet-metal shaping.
Typical defects include:
Dents
Panel height differences
Welding marks
Small holes
Scratches
Local depressions
Uneven repaired areas
Bright CHPO Body Filler is used to fill and level these areas before subsequent primer and paint application.
Its product positioning is based on four fundamental repair functions:
Fills appropriate depressions and surface defects.
Helps establish a flatter repair surface.
Allows the technician to build and refine the repaired contour.
The cured filler can be progressively sanded to prepare the surface for the next coating stage.
CHPO polyester body filler is a two-component unsaturated polyester filler system consisting of the filler component and a compatible CHPO hardener.
Bright uses:
Main filler + yellow CHPO hardener
The recommended mixing ratio is:
The hardener initiates the curing reaction after mixing.
Compared with some BPO systems, CHPO formulations generally have a relatively slower curing response. This can provide a more workable application period for conventional filling and shaping operations.
Actual working and curing time varies with:
Temperature
Humidity
Hardener amount
Application thickness
Substrate condition
Workshop ventilation
“Economy” refers primarily to product positioning and cost control, not the absence of basic repair functionality.
For conventional steel-panel repair, customers often need:
Filling
Leveling
Shaping
Sanding
They may not need a specialized filler designed for every type of alloy or difficult substrate.
Bright is therefore positioned for customers who want to control the cost of frequently consumed repair materials while maintaining the fundamental functions required for conventional body repair.
Bright is primarily recommended for:
Steel sheet
Iron sheet
Conventional steel body panels
General metal repair applications
Selected machinery and fabricated metal surfaces
Typical automotive steel panels include:
Doors
Fenders
Hoods
Trunk panels
Roof panels
Side panels
Proper surface preparation remains important.
Before application, remove contamination and prepare the substrate by appropriate:
Sanding → Cleaning → Degreasing → Surface preparation
For unusual or difficult substrates, perform an adhesion test before production use.
A typical repair process can be organized as:
Damage Assessment
↓
Sheet-Metal Straightening
↓
Welding / Metal Repair
↓
Surface Preparation
↓
↓
Sanding and Shaping
↓
Primer / Surfacer
↓
Basecoat
↓
2K Clearcoat
Bright therefore functions primarily as a filling and shaping material before primer application.
It does not replace primer, surfacer or finishing coatings.
After mechanical straightening, remaining low areas can be filled and leveled.
After appropriate weld grinding and preparation, filler can help smooth local surface irregularities.
Suitable for conventional shallow-to-moderate filling requirements within the product's intended application range.
Appropriate surface defects can be filled before sanding and subsequent coating.
The material can be used to establish a smoother transition between repaired and surrounding areas.
The exact filler thickness and number of applications should be determined by the repair condition rather than attempting to build excessive thickness in one application.
Bright is particularly relevant to conventional steel vehicle repair.
For localized dents and repaired areas after sheet-metal straightening.
For restoring the surface contour before primer application.
For conventional steel-panel filling and leveling.
For larger repaired areas requiring progressive filling and sanding.
For repairing multiple conventional surface defects before repainting.
The product is most suitable when the vehicle repair involves traditional steel bodywork rather than difficult alloy substrates.
Polyester body filler performance depends heavily on the condition of the substrate.
Before application:
Loose or active corrosion should be removed.
Contamination can interfere with adhesion.
The surface should be clean before mixing and application.
Create an appropriate mechanical surface for the repair system.
Unsound old coatings should not be used as a foundation for a new repair layer.
A technically appropriate filler cannot compensate for an unsuitable or contaminated substrate.
The recommended ratio is:
For example:
100g filler + 2g hardener
or:
500g filler + 10g hardener
Mix the two components thoroughly until the hardener is evenly distributed.
Excess hardener can shorten working time and alter the curing behavior.
Too little hardener can result in slow or incomplete curing.
For consistent workshop results, use the recommended ratio and adjust the repair quantity rather than changing the formulation.
One characteristic of CHPO systems is their relatively slower curing response compared with some faster BPO systems.
For certain conventional repair operations, this can provide additional time for:
Spreading
Contour adjustment
Edge refinement
Surface leveling
Larger-area repair work
This characteristic can be useful when the technician needs to manipulate the filler rather than immediately move to sanding.
However, curing speed is affected by environmental conditions and formulation parameters. The actual workshop process should follow the applicable technical data and operating conditions.
| Technical Factor | Bright CHPO Economy Filler | BPO Multi-Purpose Filler |
|---|---|---|
| Curing system | CHPO | BPO |
| Hardener | Yellow CHPO | Commonly red BPO |
| Primary positioning | Economical conventional repair | Multi-substrate / higher-performance repair |
| Steel | Recommended | Recommended |
| Iron | Recommended | Recommended |
| Aluminum alloy | Not a primary recommendation | More suitable when specified |
| Stainless steel | Not a primary recommendation | More suitable when specified |
| Substrate versatility | Conventional | Broader |
| Cost positioning | Economy | Generally higher |
| Curing response | Relatively slower | Often faster |
| Typical use | High-volume conventional repair | More demanding substrate applications |
The comparison should be understood as a product-positioning distinction, not as a claim that one curing system is universally better than the other.
A common mistake in product selection is treating all metal surfaces as equivalent.
Steel, aluminum alloy, stainless steel and specially coated metals can have substantially different surface characteristics.
Bright is primarily designed around conventional:
Steel + Iron + Routine Repair
For:
Aluminum alloy
Stainless steel
Special alloys
Difficult coated surfaces
a specialized filler should be considered, and substrate compatibility should be confirmed before use.
This is why Bright should not be marketed as an “all-metal universal body filler.”
Bright can be integrated into a conventional collision-repair workflow.

This makes it particularly suitable for repair shops where conventional steel-body work represents a significant portion of daily operations.
Used-car preparation frequently involves multiple conventional cosmetic repairs.
Examples include:
Old repair marks
Small dents
Scratches
Localized panel irregularities
Previous welding areas
Because body filler is consumed repeatedly during these operations, an economy-oriented formulation can be relevant when the repair does not require specialized multi-metal performance.
Bright can therefore be used as a routine workshop filler SKU for conventional refurbishment work.
Bright is not limited to automotive applications.
Subject to substrate and coating compatibility, selected applications may include:
Steel machine housings
Metal equipment panels
Steel cabinets
Iron frames
Fabricated metal components
Conventional equipment repair areas
The purpose remains the same:
Fill → Level → Sand → Prepare for Coating
For industrial applications outside the normal automotive repair environment, conduct a small-area adhesion and coating compatibility test before bulk application.
The product may also be considered for certain wood or construction repair scenarios when the substrate and subsequent coating system are compatible.
However, these applications should not be treated as equivalent to the primary automotive steel application.
Before large-area use, verify:
Substrate adhesion
Drying behavior
Sanding behavior
Compatibility with the subsequent coating
For a professional workshop, body filler can be a frequently consumed material.
A practical purchasing strategy is to separate products according to application:
Bright CHPO Economy Body Filler
Specialized BPO Multi-Purpose Filler
1K Pinhole Filler
This approach prevents a high-cost specialized filler from being used unnecessarily for every conventional repair.
| Repair Requirement | Recommended Product Direction |
|---|---|
| Conventional steel dent | Bright CHPO body filler |
| Steel panel leveling | Bright CHPO body filler |
| Routine weld-area leveling | Bright CHPO body filler |
| High-volume steel repair | Bright CHPO body filler |
| Aluminum alloy repair | Specialized multi-substrate filler |
| Difficult alloy substrate | Specialized filler after compatibility confirmation |
| Pinholes / sanding pits | 1K pinhole filler |
| Overall primer preparation | Compatible primer / surfacer |
The correct selection depends on the actual substrate and repair condition.
