Brian, please tell us more about the two Cor-Ban products. Can you share how they were selected, comparisons with other similar products, etc? In your trade, are "creep in between" inhibitors a big deal, or mere insurance, or something else?

This same experience (small scale as I tested the process) applies to many popularized processes that have been posted without warnings, or even knowing the risks. It taught me to be much more careful in my build, and not blindly copy others (applied widely). Skill and technique makes a huge difference in the outcomes of many building practices. Advance learning/testing is fundamental, or these days . . . just follow the (well written) instructions.

Sorry about taking so long to reply on this. The Cor-ban research was done by the C-5 program so I had to get some details.

The C-5 program did some testing a few years ago and had best results with Cor-Ban 35. I asked for the results but haven't gotten them yet.

Part of the reason for use of Cor-ban 35 vs something like corrosion X is that Cor-ban 35 is a dry film protectant. Corrosion X does not dry. Once Cor-ban 35 is applied it stays on the part unless damaged. It is also water displacing.

Please note we have discovered that Cor-ban should never be applied over electrical equipment as electric sparks can cause flammability issues.

Thanks for this information Brian! Look forward to hearing from you once you have the test results.
