A local machinist group has mixed up a batch and all nowof them use it with equally good results. Notice also that "Liquid Wrench" is about as good as "Kroil" for about 20% of the price. This was sent to me by email and I have not verified but am going to try the homemade mix myself.--------Jerry Dotson59 Daniel Johnson RdBaker, FL 32531Started building NX510JD July, 2009Ribs and tailfeathers doneusing Lycoming O-235Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Fri, 13 Aug 2010 11:40:09 -0700 (PDT)
