You don’t have to take our word for it. Read the Practical Sailor® review of TC-11 and competing products. TC-11 outperforms all others.
The identical steel Q-panels presented below were chemically cleaned, treated once with a competing product, and exposed to identical environmental conditions of 24-hours per day of a salt breeze, intermittent rainfall, tropical sunlight, and a nightly condensation cycle for 21 days. The panels were photographed on a daily basis to document the test results and the test can be duplicated by any interested party. A photo log of the daily test results is presented on the Seeing Is Believing web page.

See the Competition page for more examples of how TC-11 performs in comparison to other products.

Recently, one of my customers called me to repair his $6,000.00 radar. Upon inspection of the antenna, I found extensive water damage. The printed circuit boards were green with corrosion. I didn’t know if I could salvage them. Being out of the cleaner that I normally would have used, I purchased a can of TC-11. Your product, I found out, not only removed the corrosion but was easy to remove the residue. Upon reinstalling the unit, The customer thought I purchased all new boards and was ready to cash in an IRA for the repair. He was amazed that all the boards were salvaged, and the bill, including labor, was a little more than $500.00, including the $10.00 for your product. Your TC-11 will, from now on, be the only corrosion cleaner and inhibitor in my vehicles.Cal Kanyuck
A Happy TC-11 customer.
I have utilized numerous suppliers and products throughout my 55 years of experience in equipment and vehicle repair and maintenance. H&N Industries' commitment to customer satisfaction is among the best I have experienced. I sent them an email regarding a problem with a recently received TC-11 spray can. The next day, they called, apologized for the issue, and informed me that the can would be replaced. Within a week, I received not only a replacement TC-11 can, but also a free oiler and a drip bottle! Customer service doesn't get any better than this.
About their product: I live in Florida, and the humidity causes a fair amount of corrosion on equipment and tools. I have been using TC-11 for several years now because of its proven performance. TC-11 is about the only product I use for corrosion protection and basic lubrication. How good is it? Last winter, a friend borrowed my Car Hauler for a trip to New England, and while there, he traveled many miles on salted roads. When he came back, we rinsed the trailer off with water, and when dry, we sprayed the critical areas with TC-11. The trailer sits outside, and eight months later, there is no evidence of corrosion from the salty trip. TC-11 is good stuff!

Tools treated with TC-11

Every individual and every organization has a definite need for TC-11!
TC-11 is the first corrosion inhibitor to effectively:
TC-11 is an excellent semi-permanent penetrating lubricant.
TC-11 is very effective at preventing vehicle corrosion caused by road and ocean salt.
TC-11 makes electrical systems water resistant.
TC-11 removes recently set concrete from metal tools.
TC-11 removes adhesive residues, rust stains, and ink from most surfaces.
TC-11 does all this without adversely affecting rubber, paint, and plastic.
TC-11 is completely free of silicone and chlorine.
TC-11 comes off easily with soap and water or any degreasing surface cleaner.
TC-11 offers a significant performance improvement over all other corrosion inhibitors.
TC-11 is the end of "Normal Wear and Tear"
TC-11 was developed by an aerospace engineer to increase the lifetime and reliability of all types of tools and equipment at a minimal cost.
TC-11 is the only corrosion inhibitor that provides documented side-by-side test results to substantiate product performance claims. Standardized steel test panels treated once with a competing product and exposed to identical test conditions were used to generate the following test results.

This graph indicates that TC-11 offers unprecedented corrosion control performance. The TC-11 film is an excellent lubricant, so the lubrication performance of TC-11 is superior to competing bulk lubricants by the same margin as the unprecedented corrosion control performance. The rust penetrating capability of TC-11 is a function of the fact that TC-11 makes rust “float” off off the underlying metal. It has to be seen to be believed.
Dealer's Pick Award
TC-11 won the Retailer's Choice Award at the August 2002 National Hardware Convention and the Dealers Pick Award at the September 2002 Hardware Conference on Marco Island, Florida.
TC-11 enables you to:
Maintain the original appearance and performance of equipment indefinitely with a minimum of cost and effort.
