Does the inside of the wet wing tank need to be chromated before the Pro-seal is applied?
A. No, the pro-seal should be applied on a bare surface. If one has already applied the zinc chromate, then use scotch brite to remove. The zinc chromate will prevent proper sticking of the pro-seal and as a result the tanks could leak. Back to Top Q. Can acetone or other cleaning compound be used to clean the pro-seal. A. Be careful of the type of cleaning compound used as this could soften the pro-seal. As a result a proper bond won t occur and the tanks could leak.
