You may be able to pull out small dents in your car using a hot glue gun and some wooden dowels with a DIY version of what’s known as a “glue pull.”
In professional shops, a glue pull involves attaching handles to a dent with hot glue and then tugging them out with specialized tools (as demonstrated in this video). For small dents, however, YouTube user Tom demonstrates how you can perform a similar technique at home with a hot glue gun and some makeshift handles.
This method requires a bit of finesse, some trial and error, and may not be for everyone. Glue shouldn’t harm your paint job, but when you’re dealing with bending metal, fixes can get very subjective. We haven’t seen too many DIY videos for this technique, so it’s not as thoroughly tested as some other tips we’ve featured—and we’d actually recommend against using a metal hammer directly on your car as Tom does in this video—but if you’re up for venturing into semi-uncharted territory, give it a shot. Just be sure to do your research before you start and exercise caution.
