Can I use one Tank Sealer Kit on multiple fuel tanks?
Yes, you can seal multiple tanks using a single appropriately sized Tank Sealer Kit .
Be sure to fully prep both tanks first. When applying the Tank Sealer , pour part of the Tank Sealer can into one tank and immediately pour the remaining Tank Sealer portion into the second tank. Never drain Tank Sealer from one tank into another.
You may also pour a portion of the Tank Sealer into a properly prepped tank, then place painter's type plastic between the lid and the Tank Sealer can to reseal it for later use. Stored properly (cool, dry place), the remaining Tank Sealer can be reused within six months.
KBS Klean and RustBlast can be reused on multiple tanks and may be poured from one tank to the next without losing effectiveness during the preparation process.
