What is a potential problem with using wax and grease remover on bare metal before applying filler?

Using wax and grease remover on bare metal before applying filler can lead to problems primarily related to adhesion. While these removers are designed to eliminate contaminants such as oils, wax, and dirt from surfaces, they can also leave behind residues that may interfere with the bonding process between the metal and the filler.

When applying filler directly onto bare metal, it is crucial to ensure that the surface is as clean and free from any contaminants as possible. If the wax and grease remover does not evaporate entirely or leaves a slight residue, it can act as a barrier between the filler and the metal. This prevents the filler from properly adhering to the surface, which can lead to issues such as peeling, cracking, or reduced structural integrity of the repair over time.

Understanding the implications of using such products is essential for achieving a durable and effective repair in non-structural analysis and damage restoration. Proper surface preparation is a key factor in ensuring that the filler adheres correctly and performs adequately in the long term.
