I'm sure this has been discussed before, so forgive my old-timer's disease...

Is Oratex certified?
When I asked them that question at Airventure regarding what aircraft were on the STC AML, they said the 120/140 was not but they have a DER or DAR (can't remember which one she said) who can help with the approvals for a $500 fee. I did find another good pic of a 140 with Oratex. I guess the total cost is about even with other systems but the total labor required is much less and no painting unless you want to for a certain scheme.

It sure looks good in the pic, David. I'm curious about the "feel" in terms of comparing to dope/paint build-up. And, it would seem, the test of time will provide good comparison to "traditional" coverings. Having been involved in dope & fabric a few times over the years (and, I believe you have, too?), the idea of simply "gluing on, shrinking and flying" sounds good. ...I'll have to admit, though, that I do kinda like the aroma of dope ;) .

Why do you think they call it "dope"? :D

It's pretty similar with the samples I got to see. End of day, Oratex is polyester fabric where the finishing is pre-completed at the factory. Part of of they state is this approach is that it's lighter overall. Some of the colors can be a bit translucent. If you like a more traditional appearance, there are compatible finishing colors that can also be used where you might have a chance to bring that traditional aroma back in. :-)

I thought the silver in that photo looked pretty good and I would have not suspected it was Oratex versus any other system. Other differences when I asked was how you make a repair. Dents can often be addressed with application of heat. Small punctures or tears can be fixed with repair versions of the same pre-finished material that is like a sticker. Peel and stick. Larger repairs are more like original covering where you would lay in a piece and glues the edges and heat to shrink it taunt.

Mac, you're right I have some experience being around my dad growing up and restoring a Bamboo Bomber with Ceconite. I was the lucky one who got to do the wet sanding on the belly and under the wings between coats. Are far as longevity, Oratex has been on some planes now over 10 years. It gets used a lot in Alaska and in STOL type aircraft. Light weight and apparently can take a beating. As you say, time will tell. I have metal wings on the 120 but would like to acquire a set of fabric wings at some point. It's on the list.

LOL, indeed. I can't say it bothered me when I was young being around it. :D. Restoring a Bamboo Bomber took a whole lot of it too.

Saw it at Oshkosh again this year. The Ceconite is still holding up although overall, she needs some attention.

Here is the actual airplane, N88878. 1943 Cessna UC78-C

RE Cessna_UC-78C -- what a beautiful airplane! ...a LOT of surface for sanding "upside down" on the one that you "helped" with -- that was real child abuse, David! :lol: . Seriously, great experience and blessings to have worked with your dad, I know you agree. Some of my "dope & fabric" work was with an A&P/IA whose day job was utilizing his Ph.D. in toxicology for a major paper products manufacturer -- he always assured me ("trust me, I'm a doctor" ;) ) that we were "safe" breathing those fumes...but, I recall that we both did sneeze and cough a lot afterward. I'm liking Oratex more and more! ;) Mac

This might give an idea of what a finished surface looks like.

Been on since 2016 and still looks like new. Im definately an advocate of the product.

Thanks, Graham -- that wing sure looks good! How much weather exposure have you had since the '16 installation?

With that kind of care and protection, this is going to become known as the "new" lifetime fabric! It sure appears to be a great choice for all to consider, especially if "approvals" are made relatively simple or wider list of STCs are coming. Thanks for sharing the info. and pics! Nice work!
