Yes — a single appropriately sized Tank Sealer Kit can seal multiple tanks. The key is proper timing and technique during the application process.
Be sure to fully prep both tanks first. Then pour a portion of the Tank Sealer into the first tank and the remaining portion into the second tank immediately.
⚠ Important Never drain Tank Sealer from one tank into another. Divide it from the can and apply to each tank simultaneously. |
If you need to seal a second tank at a later date, pour the first portion of Tank Sealer into the prepped tank, then place a piece of plastic between the lid and the opening of the can before resealing it.
💡 Pro Tip Tank Sealer stored with a plastic barrier between the lid and the can will stay usable for up to six months. |
KBS Klean and RustBlast are more flexible — both can be poured from one tank to the next and used across multiple tanks without losing effectiveness. You can typically prep several tanks from a single treatment.
