When they cut it off and threw it in a landfill, where ever that is, I'll guarantee the fabric is still in good shape.

Can you elaborate. Did some Superflite here and really like the glue. Attached the fabric, stittched and then taped, sprayed pimer which needed little sanding and painted color. Seemed like less work to me.

Curious to what your experience was Mike. I usually use Polyfiber, have used dope and Airtec. ???
You'll have to email him, I don't think he lists it on his website but it's a good kit. He'll send you some of the drawings if you email him.
Covering Systems (an updated list):
- poly-fiber
- steward systems
- oratex
- superflite
- star gloss
Joel - the guy who delivered the Javron wings this AM mentioned Star Gloss as being a re-branding of poly-fiber.. not sure if there's a difference between the two?

there is another system you have not listed. Airtec. It is a urethane paint and the system was originally designed for crop dusters so it is quite durable. Very high gloss. Acetone based so much less toxic than the MEK based systems. Only two steps. Primer which sands very nicely, wet. And the topcoat. I’ve tried several systems and I like it. Just my opinion but you might at least consider it.
Hope this helps

Polyfiber, Stits, or one of the "normal" traditional coverings definitely hold up the best at least if parked outside and are the most cost conscious. A good friend who had done quite a few covering jobs with both Polyfiber and Oratex found that the Oratex is very difficult to work with, especially gluing the tapes down. Plus Oratex is at least double the cost of any other system in materials alone.
No Stewarts system, not ever. I know some will disagree and to that I'll send you pictures and video of popping big water "blisters" on the wings of my brother's Tcrate. This is a fairly common occurrence and they always blame the person doing the covering job for not doing it right but it's still a common problem. Common enough that I'd stay away. I swear that poor crate has probably another 10lbs of water under the paint every time it gets parked. Preflight consists of going around draining paint blisters like popping zits.

Not with the original procedure of sealing the fabric, which is what they went back to.

You really should take another look at it. It is a very easy system to apply.

A whole extra step? It's the same amount of steps as Polyfiber, in fact less steps than Polyfiber for what that's worth. :roll: Seal the weave with the diluted cement like we did from day one and everything is fine. They were trying to eliminate that step and just seal with the Ekofill, and there have been problems with that in certain climates. Of the thousands of jobs done with it, a few have had issues, and not fun issues at all. That's why it's back to sealing with the cement.

Thanks Bill, I will add Airtec to the list. Also like to thank you for the forum about building javron wings, I'll be following that when I build mine. I've seen your videos from float flying Alaska, inspirational!
An update:
I've got most of the tail feathers welded up, with the exception of the elevators, which I decided to skip so I could start working on the fuselage. First step is to tack the firewall square and stand it up vertical where it needs to go on my table. Then I can start to fit the lower section of the fuselage together from the firewall back. I talked with a guy who build three of these VR3 fuselages, you may have seen his threat from years ago on here. This is the way he said to do it. Tack the firewall then you can fit the fuselage clusters together like legos. He said they used the clear cellophane wrap to hold the longerongs and cross tubes together before tacking. He said by fitting the whole lower part of the fuselage before tacking it will be clear if it's not strait because a cluster won't fit perfectly. Also said to use a plumb bob and mark a centerline on the cross tubes and down the center of the table before starting. So that's the plan for 2021, try to finish the welding. 2022 (or whenever I get the welding done) I'll start building the javron wings.
Also, I will be starting on my PPL here on the 14th. Training in a 172 at KEUL, part 141. The plan is to fly 2-3 days a week and knock out the PPL. Then eventually I'll get my tail wheel and do some backcountry training. I know one CFI locally who will do those together, although he has a long waitlist. End goal is to be able to go into some of the Idaho grass strips with my cub. Really not wanting to land on maintain sides like the youtubers, just see some more of the state.

make sure you have clearance to get a socket on engine mount stud bolts going through firewall... it's a tight spot (on top ones?)...
Mrunia, how's your progress with covid in the rearview?
Oratex is nice stuff but you really need to take your time to make it look right. It gets dirty easily, similar to polytone. We do it, and the other systems here. Stargloss is a PF product that uses ranthane or aerothane as a top coat. It really puts the polyfiber system on par with airtec and superflight. I hope you've made it to the covering phase.
