Tank Sealer Questions and Answers
Can Tank Sealer Be Used on an Air Compressor Tank?
Yes, KBS Tank Sealer stops condensation rust and seals pinhole leaks in air compressor tanks.
Can I Coat a Plastic or Polyethylene Gas Tank?
Yes, plastic and polyethylene tanks can be sealed with a modified process that adds Fusion SEP as an adhesion promoter.
Do I Need to Remove a Previous Coating First?
Yes, strip out a previous liner with KBS Strip before sealing, since Tank Sealer needs a bare, prepped surface to bond.
Is Surface Rust After RustBlast Normal?
Yes, light surface rust after rinsing RustBlast is normal flash rust from moisture in the air, and it will not affect the seal.
Can I Reuse the KBS Klean Solution?
Yes, drained KBS Klean solution can be filtered and reused, often for up to ten cleanings from the same batch.
What Is the BackBone Mesh For?
BackBone Fiberglass Mesh reinforces pinholes and weak spots, embedded into wet Tank Sealer for extra strength.
What Is the Minimum Application Temperature?
Apply all three steps above 55 degrees F, with best results up to 80 degrees F.
What Dilution Ratio Should I Use to Clean a Tank?
Use KBS Klean full strength, 1 to 1 with hot water, for tank interior cleaning, not the standard 10 to 1 dilution used elsewhere.
Why Are There Black Streaks When I Stir It?
Black streaks while stirring are normal leafing aluminum pigment behavior, not contamination, and they disappear once the sealer settles or cures.
Can I Split One Kit Between Multiple Tanks?
Yes, a single kit can seal multiple tanks if both are fully prepped first and the sealer is portioned out with proper timing.
Can I Skip KBS Klean and RustBlast?
Tank Sealer can technically go on without KBS Klean and RustBlast, but skipping prep risks poor adhesion and early failure.
Can I Use Tank Sealer on a Brand New Tank?
Yes, even a brand new tank should get the full 3-step system, since an uncoated tank will eventually rust from the inside.
Can I Use Tank Sealer on a Bio-Diesel Tank?
Yes, Tank Sealer is completely impervious to bio-diesel and standard diesel fuel.
Can Tank Sealer Be Used on Oil Tanks?
Yes, Tank Sealer is widely used on oil tanks; thorough prep to remove oil residue is the key to long-term performance.
