FAQs
Can I use HB Body 290 on plastic bumpers?
No, this filler is specifically designed for metallic surfaces and may not adhere correctly to flexible plastic.
What is the recommended grit for sanding?
Start with P180 grit sandpaper for initial leveling and shaping.
Does the kit come with a mixing board?
The kit includes the filler and the BPO hardener; mixing tools and boards are typically sold separately.
How long do I have to work with the filler after mixing?
Pot life depends on temperature, but generally, you should work efficiently as it begins to set relatively quickly after the hardener is added.
Can I apply this over old paint?
It is best practice to sand down to the bare metal or a compatible primer layer for the strongest possible bond.
Is this filler waterproof?
Once cured and properly top-coated with primer and paint, it provides a durable, weather-resistant barrier.
Troubleshooting
Filler is not curing or remains tacky
Verify the mixing ratio of BPO hardener. If it is too low, the mixture will not cure. Ensure temperatures are above the recommended minimums.
Surface cracking shortly after application
Ensure the underlying metal was properly cleaned and free of moisture or oil, which can prevent adhesion.
Pinholes appearing after sanding
Apply the filler in thinner layers and ensure the mixture is thoroughly worked into the surface to prevent air pockets.

Setup, Compatibility & Care
To use the HB Body 290, you must thoroughly mix the filler with the provided BPO hardener on a clean mixing board. Always follow the manufacturer's specified ratio, as under- or over-catalyzing can lead to soft spots or improper hardening.
Compatibility: This product is specifically formulated for metallic substrates. Always ensure the metal is free of rust, grease, and debris before application.
Care: Store the container in a cool, dry place away from direct sunlight and heat sources to maintain the shelf life of the resin. Keep the lid tightly sealed after every use to prevent solvent evaporation.
