Essential Rust Repair Guidance

How safe are the POR-15 Stop Rust Kit components?

The POR-15 kit includes a Cleaner Degreaser and Rust Preventive Coating. While effective, users should wear gloves and work in a well-ventilated area to avoid inhaling fumes.

Is the Eastwood Rust Encapsulator Plus suitable for all surfaces?

Yes, it bonds well to rusted metal. However, for optimal results, ensure the surface is clean and free from loose rust before application, as this enhances adhesion.

Can Bondo Fiberglass Resin Repair Kit be used on wet surfaces?

No, it shouldn't be applied on wet surfaces. The resin needs a dry, clean area to cure properly, ensuring a solid bond for long-lasting repairs.

Are there any special safety precautions for using fiberglass resin?

Absolutely. When using the Bondo kit, always wear gloves and a mask. Fiberglass dust can irritate skin and lungs, so take care to protect yourself.
