FAQ — quick answers

Q: Will this fix white smoke from exhaust?

A: If the white smoke is from a head gasket / coolant leak, this product often reduces or stops the symptom by sealing the leak. Not a guaranteed cure for catastrophic failures.

Q: Can I drive after application?

A: Yes — drive normally after the treatment. Full cure improves with regular engine operation over the following days.

Q: Refund / Guarantee?

A: Lifetime money-back guarantee subject to terms — see product listing for claim conditions (proof of purchase & evidence of attempted repair may be required).
