How-To Guide:
Step 1: Before starting work on the repair, make sure the damaged area is thoroughly cleaned and free of grease, oil and dirt. We recommend the use of Belzona 9111 and a stiff bristle brush to remove all the surface contaminants.
Step 2: Terminate all cracks by drilling holes along the length of the cracks and at both ends. This helps to prevent crack propagation.
Step 3: Insert studs into holes and using a grinder, cut all the studs flush with the casing.
Step 4: ‘Vee’ out all the cracks with a hand-held machine fitted with a cutting disc and roughen the entire repair area to ensure excellent adhesion of the Belzona repair material.
Step 5: Once again, clean and degrease the repair area and apply masking tape to the area to be repaired.
Step 6: Measure and cut a piece of Belzona 9341 to the size of the masked off repair area.
Step 7: Mix the appropriate amount of Belzona 1111 making sure to achieve a uniform material (Learn more about mixing and applying Belzona 1111 (Super Metal) here: http://belzona.com/ViewFile.aspx?id=51037)
Step 8: Apply a thin layer of Belzona 1111 to the prepared surfaces pressing firmly with a stiff bristled brush to ensure full contact with the surface.
Step 9: Wet out the Belzona 9341 with the mixed Belzona material and bed it down over the crack into the layer of Belzona already applied using an applicator.
Step 10: Apply another layer of Belzona material to create a buildup of approximately 1/8th inch (3mm) over the entire area. 
Step 11: Remove the masking tape and leave the repair to cure. After the product is fully cured, the engine is ready to be put back to service!
