I’m doing some body filler repair for the first time in my life. Nothing major, just very minor paint bubbles under the rocker in a small place or two. I’ve already completed a couple spots and have a couple more to go. I’m using Bondo and regardless how little hardner I use. The filler hardens entirely too quick. It might be the humidity in my garage. Pretty humid. If you don’t use any hardener will the Bondo dry completely ? I understand at the very least it will take a long time. But, does it completely dry eventually ? I’m not in a hurry. It’s my personal car that i’m just touching up a few very minor spots.
