Where the price can move
Heavily pitted or scaled metal soaks up more product — plan for a second coat and roughly 30% more than the flat-surface figure. Rough cast iron behaves the same way.
Conversely, light surface bloom on smooth steel can stretch past the stated coverage, because you only need a thin film for the reaction to complete.

Frequently asked questions
Why is the 8-pack so much cheaper per bottle?
Shipping and handling are the fixed costs. Sending eight bottles in one carton costs far less than eight separate orders, and we pass that through.
Are there hidden fees?
No. The total shown before you pay is the total charged. Any local import duty is set by your country, not by us.
Do prices include shipping?
Tracked shipping is free on the 3-pack and above. Smaller orders show the shipping cost before payment.
Is there a trade or bulk price?
For quantities beyond the 8-pack, email support@getrustguard.com with your requirement.
