FAQs
-
Is Bondo waterproof?
Some Bondo fillers are waterproof, such as our Short and Long Strand Reinforced Fiberglass Fillers and our Liquid Resin for Fiberglass. Others are not waterproof, and we recommend keeping them dry until final finishing and sealing.
-
Does Bondo seal rust?
Bondo seals holes and repairs damage caused by rust, but before it can be applied, the rust needs to be completely removed.
-
Where should I store Bondo?
Store Bondo in a cool, dry place with a consistent room temperature. Bondo that's stored in places like uninsulated garages may experience extreme heat and/or cold, which will affect its shelf life.
-
Can you paint over Bondo without primer?
No. Primer keeps Bondo from absorbing paint and prevents dark spots in the repair.
-
Is it normal for Bondo to warm up when it's mixed?
Yes, the chemical reaction between the filler and hardener generates some heat. As you mix, keeping the mixture spread thin across your mixing board will give a slight increase in working time.
-
Should I wear a mask/gloves when using Bondo?
Not required, but highly recommended. When donned correctly, a respirator may help protect from fumes if not working in a well-ventilated area.
-
What is the maximum thickness I can apply Bondo?
As a guideline, maximum filler thickness of Bondo should not exceed 1/4 inch.
-
Can Bondo be applied to a painted surface?
It's recommended that Bondo be applied to a surface where the paint is sanded to the bare metal or substrate. It is also acceptable to apply Bondo Filler over the top of automotive epoxy primer.
-
I opened the Bondo can and it's not filled to the top - why?
Bondo Filler is sold by weight. It is normal for the filler not to reach the top of the can and allows room for mixing without spillage.
-
I'm missing parts of my kit or directions/purchased expired product/ordered product that arrived broken.
If you are missing accessories or DFUs, purchased expired filler, or if your filler arrived broken, please contact 1-888-3M-HELPS.
