Frequently Asked Questions

Q: Can this welding-grade casting adhesive be used on aluminum as well as cast iron?

A: Yes. This casting adhesive is formulated to work on a wide range of metals including cast iron, aluminum, and steel. It's suitable for filling porosity, cracks, voids, and other casting defects on most common metal types found in automotive, industrial, and general workshop applications.

Q: Do I need any special equipment or a power supply to use this metal repair adhesive?

A: No special equipment or power supply is needed. This liquid casting adhesive is a no-weld solution — simply apply it to the cleaned and prepped metal surface. This makes it ideal for field repairs and for users who don't have access to welding equipment.

Q: Can the cured adhesive really be machined, drilled, and painted?

A: Yes. Once fully cured, this welding-grade casting adhesive achieves a hardness and density that allows it to be machined, ground, drilled, tapped, and painted just like the surrounding base metal, allowing for a professional, seamless repair finish.
