FAQs
What is the shelf life of the Stevens Bridger SB-1?
When stored correctly in sealed containers in a cool, dry environment, the filler and hardener typically maintain their effectiveness for at least one year. Always check batch dates if available.
How long does it take for the filler to cure?
Curing times vary based on temperature, humidity, and the ratio of hardener used. Typically, it becomes sandable within 20-30 minutes under ideal conditions (around 20°C/68°F).
Can this filler be used on plastic bumpers?
This specific formula is designed for metal body panels. For plastic parts, a flexible plastic repair filler or adhesive would be more appropriate.
What grit sandpaper should I use for shaping?
Start with a coarser grit (e.g., 80-120 grit) for initial shaping and then move to finer grits (e.g., 180-320 grit) to smooth the surface before priming.
How much hardener should I use?
Always refer to the product packaging or manufacturer's technical data sheet for the precise mixing ratio. Incorrect ratios will significantly impact performance and curing.
Can I apply this filler over existing paint?
It's best applied to bare metal or properly prepared surfaces. If applying over existing paint, ensure the paint is well-adhered, sanded, and clean. It is not recommended for direct application over loose or flaking paint.
Troubleshooting
Filler not hardening or curing slowly
Ensure the correct ratio of hardener was used and mixed thoroughly. Check that the ambient temperature is within the recommended range for application and curing. Old or contaminated hardener can also reduce effectiveness.
Filler is too hard to spread immediately
You may have used too much hardener or mixed it too vigorously, causing it to start curing prematurely. Mix smaller batches more quickly or ensure the correct ratios are precisely followed.
Poor adhesion to the surface
The repair surface was not properly prepared. Ensure it is clean, dry, and free from contaminants like oil, grease, or loose paint. Mechanical abrasion (sanding) is often required for optimal adhesion.
Shrinkage after curing
Applied too thick a layer at once. It's best to apply filler in thin, successive layers, allowing each to partially cure before applying the next. Ensure the area is properly supported.

Setup, Compatibility & Care
Setup:
- Ensure the repair area is clean, dry, and free from grease and rust.
- Measure the filler and hardener according to the manufacturer's instructions (typically a specific ratio by weight or volume).
- Mix thoroughly on a clean, flat surface until a uniform color is achieved. Avoid over-mixing which can introduce air bubbles.
- Apply the mixed filler immediately to the prepared area using a suitable spreader.
Compatibility:
- Designed for use on automotive metal body panels.
- Compatible with most standard automotive primers and paints after curing and sanding.
Care:
- Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Keep containers tightly sealed when not in use to prevent drying out or contamination.
- Clean tools immediately after use with appropriate solvents as recommended by the manufacturer.
