What about SuperFlite? Same Dacron, but no silver coats. Certified, Sean Tucker uses it. Any direct experience out there? Was going to use it on my soon-to-be Skybolt. We have a newer Citabria with Superflite on it. American Champion used it when the airplane was built in '96, and have since gone away from it, they tell me. I don't know why, but I will tell you that it seems obscenely expensive. I had to buy enough to make a small repair on the aft fuselage after the tailpost broke and was repaired, and the materials came to $900. I do have some left over, but I bought the smallest quantities I could. I think you'd want to compare the overall costs between it and some of the other systems before you buy. Dan |

I redid a TriPacer in SuperFlite once. It is the process of choice for the total amateur. There is no silver. There is no sanding. You shoot three base coats of the brown stuff (the UV protectant - instead of Aluminum flakes it is a chemical blocker) and then a topcoat (if you want a topcoat). It is a pain in the ass to repair - about like PolyGloss (the glossy topcoat in Stits, what you see on all the Oshkosh champions - the non- glossy topcoat is serviceable but not really very pretty) and harder than anything else. Certainly much harder to repair than dope (Randolph makes that these days). The instruction manuals are not so great - not at all like the fine book you get with Stits - but adequate. I've been involved with dope and Stits repair and rework jobs too, and I must say by comparison SuperFlite is easier to do and less work. The finished product is airworthy and safe, but it's not as pretty as a good glossy Stits job. Michael |

Michael I wonder about the long-term viability of chemical UV blockers. don't they sacrifice themselves to UV, rather than simply reflect the UV, as aluminum powder does? Just what is the objection to the use of aluminum dope, anyway? It is easy to apply, easy to determine if you have sufficient coverage and easy (with a lot of wet sanding) to get a good finish. -- Remove _'s from email address to talk to me. |

I haven't heard of any fabric covered planes going down like the Hindenburg, but the aluminum powder mix used in the Hindenburg's covering paint was the main cause of it's destruction, it seems. Hmm.

Their latest version of the stuff is called System VI and has a white UV primer. Dan |

Early dopes were mostly cellulose nitrate and were rather explosively flammable. Butyrate dopes fixed that somewhat but they still burn merrily. Stits (Poly-Fiber) is self-extinguishing, being PVC (polyvinyl chloride, or more commonly known as vinyl). The Stits video shows a demonstration of the two being set afire; quite convincing. Dan |

The Hindenburg when up in flames because it was full of Hydrogen. You're both right. The initial ignition source was a probably a spark that lit hydrogen in, or leaking from, one or more of the lifting cells. The visible fire and smoke, and the fuel for the worst part of the fire, was the fabric covering. It used a nitrate dope that included aluminum powder, and to make things worse, the envelope was coated on the inside with iron oxide powder. Chemical reaction between the dope and the fabric produced something similar to solid rocket fuel. A couple of U.S. Navy airships, using helium lifting gas, burned in similar fashion in accidents; their fabric envelopes were also painted with aluminum powder-containing nitrate dope. |

What are the choices out there? What are the pros and cons of each? What is your recommendation? Which are easier for the applicator? Cost comparisons? I hope to get some responses, I'll also check the archive while I wait for the responses. Thanks to all who respond. Wil A lot of very good comments. Keep it up guys, thank you. Wil |
