We are the manufacturers of EZ Grip Friction Drops, Aircraft Grade and are located in the U.S. I stumbled on this thread by accident and wanted to be of help. In the
FAQ section of our web page at
www.ezgrip.net you will see that just having gritty stuff (crud in some juice or paste) is not going to work well. Friction Drops are really a tool more than a chemical. The hardened micrscopic blocks that do the work need to get into place within differential surfaces quickly and temporarily lock together when pressure is applied. Particles too brittle will only crack and not hardened blocks will only round with pressure and create more trouble. Friction Drops have no silicone in their carrier so as not to interfere with priming/painting operations later (view "ASTM Test results" on our page). Stuff used on aircraft should be approved for aircraft. Unfortuantely our international distributors have to land the product and mark it up to make profit. We will sell and ship to Europe but the cheapest way is via US Postal who charge from 9 to 10 dollars to get it there.
