What fabric to use

[Marty57]

I have done it with good results. I did learn the hardway to let the paper cool before peeling it off.

If you use Teflon paper rather than parchment paper, you will avoid the issue of sticking.

I just put that in my cart.

I have heated up wrinkles so hot that the yellow started to get dark. When it cooled the color returned. That was two years ago on a gear leg - so far, so good. Parchment, over Stitts and Airtech.

To me it all depends on how you’re going to use the plane. If you do a lot of off airport landing and have a good chance of fabric damage pick a process that’s easy to repair. Like Superflight is not as easy to repair as polyfiber my 2c worth. Had both liked the wet paint look until I had to repair it.

It's out in the shop, maybe I mis remembered and it was Teflon not silicone paper, but I learned it here...., and it worked, without harming the PolyTone finish. I got it on Amazon, cheap, and have a few 12" squares left, I'd be happy to put one in a business envelope and mail it to anyone that wants to try it. PM me.

Teflon heat transfer sheet works worlds better than parchment paper.

I learned about the Teflon Paper in Hardtail's class. (See post #6.) I learned how to cover there too.....and paint....using Stewarts. BTW, I had not covered nor even held a paint gun in my hand prior to this class.

No matter what system you choose take its class and make sure you get to shoot the paint. (I doubt Polyfiber's Sport Air workshop shoots coatings.) I've said this before, you can do this but you need mentoring. The outcome will effect the value of your aircraft from bad to good in the five digit range which exceeds the cost of the materials or the 3 day class, plus you come away with a priceless relationship with an expert in the field whom you can have as a mentor.

Hardtail are you still doing the covering class?
If so can you share details. Thanks

Question, What type of fabric is the blue stuff?
Poly and Ceconite are white.
The old Blue River 7600 fabric was yellow.
I picked up a set of wings that are painted in Imron and the fabric under this paint is a blue color, not white or yellow.

I used the Blue River process and painted it with Endura. Lasted 30 yrs easy. The blue river fabric and glues worked very nice. Water base glue was very user friendly. I'm guessing the Stewarts is similar based on what's being said, I actually haven't used it. I would do it again.

Most of the blue fabrics I have seen are Razorback. That is a fiberglass style cloth system. Not even sure if it’s still available.

I assume you are familiar with the blue look of dac proof that is used in the Randolph dope, process over ceconite?

[Ron Graham]

No, it's not razorback. I'm familiar with that.
Thanks

I'm not familiar with the Randolph stuff so it could very well be that.
All of my work has been Stits other than the Blue River I mentioned.

[supercrow]

In the Randolph dope process, it is brushed on the bare fabric before the silver spray coats are applied. Silver does not stick to that particular coating as well as some others. I have seen some separations at that point over the years and blue is what it goes to. Sometimes I have seen the paint and the silver come loose and you will see the blue coating and it appears blue tint from the bottom side.

Yes I am! Next one coming up will be May 26-28 here at my hangar in Montana. Then no more from me until I'm done putting up hay in the fall.

The Randolph process uses blue dope I believe

[PA-22/20-160]

The old Cooper/superflite dope used dac proof as the 1st brush coat that was blue. Randolph uses rand-o-proof that is green tinted nitrate, they might have had blue once, it’s all the same stuff just color added.

The different colors, blue and green, were for different dopes as the first coat on dacron fabric. Nitrate or Butyrate ... I forget which color was for which. Prior to these special first coats being developed, when dope was being applied directly to the dacron, it was possible for the entire finish to peel off in sheets down to the bare fabric. The issue was the dacron fiber would not absorb the dope in the fibers. The dope would just sit on the surface. With natural fibers such as cotton or linen the dope would soak into the fabric becoming fully attached.

[PA-22/20-160]

I’m very familiar with the dope systems and both dac prof and rand-o-prof are nitrate dope used as the 1st coats, butyrate will not stick to Dacron fabric.

I ordered some and my daughter tried it today. She didn't like it as well as the parchment paper on Poly-Fiber up through silver. Did take a small piece off and leaves an imprint of the weave in the Poly-Spray.

[bob turner]

Thanks for the tip. I almost sprung for some.

Where are you located, or where would you do the training/class?

Steve, I checked and found some that had a pattern in it too that I'd ordered...and like you say, it left an imprint. The other stuff I have has no pattern and leaves no mark. I guess it's definitely a factor, so I'll have to figure out the exact part number of the "good stuff".

Thanks, I ordered off the link above. Good to know there are differences. She is picky so if I change her process it better work and look better or she won't be happy. She was putting dollies over sea plane grommets yesterday, she wasn't very happy.

[bob turner]

I have found that doilies over seaplane grommets are essential - especially in the propwash.

I agree with you. It took a little experimenting to put them on with the Stewart’s system but I figured it out pretty quickly.
