Here’s What Other Customers are Saying…

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 then $500.00, including the $10.00 for your product. Your TC-11 will, from now on, be the only cleaner in my vehicles.

TC-11 is a great product! I saw in a Practical Sailor review for a lubricant/protectant TC-11 as a corrosion protector. They sprayed a bunch of cheap radios with different products and then put them on a board inside a saltwater aquarium just above the water. Only the radio with TC-11 survived, most turned to rust. Anyway, I bought a can and have been happily using it around the boat for now over a year. Seems to work as described preventing rust and works very well on freeing up things that have seized. Spray it on a frozen bolt, walk away for 30 minutes, and then come back and typically it does the job. I also found it excellent as a spray protectant/polish on stainless steel surfaces (we’ve got a stainless fridge and it gets all of the smudges off). It doesn’t form a film like Boeshield or become sticky like many of the other products. I basically use it whenever I take anything apart and I’m putting it back together, except for dissimilar metals where you’d need a specialized product. I also give a quick spritz on the exterior metal fittings on standing rigging, clasps, hooks, turnbuckles, etc. My wife’s central locking system was sticking and unable to unlock the doors, a squirt and it’s resolved, door squeaks, fixed. What can I say, live on a boat for 10 years and something that helps stop rust is absolutely lovely.

TC-11…Nothing works better!

We tried TC-11 in July of 2001 and it has been so effective in controlling corrosion that we now offer it as an optional treatment for all of our customers. Some customers, such as dealers for Caterpillar and Case, insist upon TC-11 being applied to every piece of equipment that is put on a barge for shipment. Our customers inform us that TC-11 is highly effective in controlling rust, and best of all, it is easy to remove without the need for soap or degreasers .
