I'm looking at using a product called Calyx manifold dressing. It's graphite based and you rub it onto the cast iron manifold. It protects the manifold from rusting and gives it a natural look.

The stacks on my A65 were standard Aeronca Champ type mild steel stacks with the aluminized heat muff. They began to show rust spots and pinholes so I sandblasted them and painted them with flat white rattle can VHT exhaust system paint. I had access to a controlled temperature industrial oven so I was able to cure them at the specified temperature for the specified duration. I ran them for another year or two and again started to see rust through the paint so I pulled them and had a talented fabricator use them as the patterns for a stainless steel set. This fellow fabricated custom stainless exhausts for all sorts of engines that were run in engine test cells, everything from big diesels to single-cylinder snowmobile and motorcycle engines. Before I could run the new stacks I swapped out my engine for an A75 and put the new SS stacks on it instead. I had already purchased some Turbo-X from Techline Coatings to spiff them up, but I never bothered... the Turbo-X is still on my shelf and my stacks still look like they did after I got them and ran them up to temperature on a couple of flights. I kind of like the color they've taken on and they sure don't show any sign of corroding. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=493946#493946 Attachments: http://forums.matronics.com//files/a75final002_830.jpg ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
