While Bondo can be a temporary fix in some situations, it’s crucial to understand its limitations and when a more permanent solution is necessary. Using Bondo incorrectly can actually worsen the problem in the long run.

Furthermore, it doesn’t address the underlying cause of the rust, which will continue to spread underneath the Bondo.
