We Conduct Hands-on Workshops.

Throughout the US and Canada we conduct how-to workshops sponsored by our distributors, EAA SportAir Center. Our mini-workshops are also incorporated into major airshows and fly-ins like Oshkosh, Sun 'n Fun, Copperstate, Arlington, and the LAA Rally in Sywell, England.

There's An Instructional Video.

This new EAA Sportair two-hour comprehensive video presents every aspect of our Poly-Fiber fabric covering process in detail and in easy-to-understand language. From preparing the airplane for covering to spraying on the colors, you are guided step by step through the entire process by a professional EAA Sportair fabric instructor. Covers: preparing surfaces, attaching the fabric, tightening the fabric, applying the first coat of Poly-Brush, tying rib-lacing knots, applying finishing tapes, spraying Poly-Spray, applying color coats.

"Why should I use Poly-Fiber?"

Poly-Fiber is the only all-VINYL system on the market today. As it dries, it bonds extremely well to today's polyester fabrics and remains flexible.

Poly-Fiber does not support combustion.

Poly-Fiber is one of the lightest systems available. Only eight coats are used. There are lightweight options, too.

Poly-Fiber is the most repairable of all systems available today, and the repairs are as strong as the original.

Poly-Fiber can be rejuvenated after years of weathering.

It has over 30 years of success as the Stits Poly-Fiber system. Many original jobs done 30 years ago are still going strong.

Poly-Fiber is not particularly sensitive to heat, cold, or humidity during application or throughout its service life.

Poly-Fiber offers choices in fabric weights and types of top coat paints. There are 50 top coat colors in Poly-Tone, Aero-Thane and Randolph Ranthane.

Poly-Fiber has options for every aircraft from a simple ultralight to the most sophisticated warbird.

"What will it cost to cover my airplane?"

Cub-size airplanes usually run about $5,000 to $5,500.

A Stearman will run about $10,000.

An ultralight may cost as little as $1,500 to $2,000.

"Is Poly-Fiber more expensive than other systems?"

No, they all cost about the same! Although dope costs less per can than Poly-Fiber, you use twice as much dope as Poly-Fiber. Price them out for yourself. You'll find they pretty much even out.

"How many steps are there?"

There are just six basic steps:

Glue on the fabric with our Poly-Tak fabric cement; tighten it with the heat of a calibrated clothing iron.

Brush on a coat of Poly-Brush fabric sealer.

Riblace, then apply gussets and finishing tapes with more Poly-Brush.

Spray on two more coats of Poly-Brush.

Spray on three cross coats of silver Poly-Spray to block ultraviolet radiation.

Spray on three coats of top coat paint, either Poly-Tone, Aero-Thane or Ranthane.

"That's six coats. How much does that weigh?"

Surprising little. Total fabric and coating weight is about 60 pounds, not the usual 75. Smaller aircraft and ultralights average about 20 to 25 pounds. For extreme ultralights it's possible to skip some steps and get down to 12 to 15 pounds, but this covering won't have all the capabilities of the full eight-coat system.

"Can I use automotive paint over a Poly-Fiber base?"

Since 2001, the FAA has required that fabric covered aircraft (at least the fabric parts) be painted only with topcoat paints tested and approved on an STC. Use of any other topcoat paint will void the STC and airworthiness of the aircraft. Up to 2001, the STC's "ended with the silver", and any type paint was legal to use. This is no longer true. Over the years, increased use of brittle automotive or industrial paints caused enough cracking and delamination to cause the FAA to rethink approving untested topcoat paints over fabric. Failed topcoat paints expose polyester fabric to sunlight and UV damage. As of the latest revision of the Poly Fiber STC Procedure Manual (revision 21, September 2006), only the following topcoat paints are approved on the Poly Fiber STC: Poly Tone, Aerothane, or Randolph Ranthane. All three of these paints have long service lives over fabric as well as an FAA Parts Manufacturing Authority (PMA), which allows their application on certified aircraft. For instance, a J-3 Cub must have only Poly Tone, Aerothane or Ranthane over the fabric parts, but you could use enamel or anything else over the struts, cowl, fairings, etc. The keyword is FABRIC. Experimental aircraft are not bound by these rules, however, we do recommend using products with known track records on fabric components.

Our primary goal is to provide you with the products you need to cover your airplane PLUS the clear concise instruction you need to use those products to complete the job.
