    Should have used Stewart Systems Ekopoly..... waterborne polyurethane.

    Consolidated coatings was having problems getting the resins for Ranthane recently as is Air-Tec on the polyurethane as of yesterday.

    After the disaster on my new tail feathers (covered and painted by an IA who has done a LOT of stewarts paint/finish process) I wont ever use it again. If you mess up with polytone you can wipe it off with a rag and MEK or acetone and shoot right over it again. Trying to deal with wrinkles and bubbles with the stewarts paint is a pain in the back side and the only way I can see to fix it right is to strip and recover the brand new recover job.

    Wasn't the OP's problem shipping?

    I personally do not have the skill to shoot the Stewarts top coat, but I have seen really nice results on small surfaces. I do like the glue and Ekofill. They should include non-tautening Butyrate so amateurs can benefit from the process and still have a nice looking finish.

    I am truly an amateur - I average a Cub every ten years, and probably have only one more cover job in me - the final coat will be Butyrate. Wet-sanded, compounded, and polished.

    I teach fabric covering and paint for Stewarts. I'm amazed when I read about the issues some have. If properly trained, there isn't really much that can go wrong if you follow the manual. As for amateurs; here's a Citabria that was recovered (fuselage) by a couple who attended one of my three day seminars. They had never covered or painted a plane before. They didn't remove the engine and shot the fuselage in a homemade paint boot from 2x4's and plastic sheeting. 330 hours over a three month period in the winter in Canada. I bet, without proper training of following their manual, I would screw up a Poly finish. I'm doing another three day next month; it's the best way to learn.

    My buddy went to Marty’s for training - made the paint booth. Put in lots of lights. Used exactly the recommended equipment - giant compressor. Airplane looks great at 20 feet. Up close - lots of flaws. He really, really worked at it. I flew it today - great fun! Just don’t look too close.

    You really do not have to be precise to shoot Poly Tone or dope - just hose it on. If you get a run, wipe it or sand later, and compound.

    There are definitely flaws in my Stewarts finish. But I'm blaming myself - mostly due to putting it on too heavy in a single coat.

    As I recall, he came for a one day paint intro at my shop, not a three day seminar. Also, he was shooting in high heat and the conditions were not appropriate for painting; over 90 degrees on some days. Like anything else Bob, facts are better than fiction and following the proper steps will produce a great finish with any system and a poor finish when the proper procedures are not followed. Sorry to be off topic but I had to address this comment.

    I just love it..Never an issue with the product, just the guy applying it. The guy that shot my tail feathers has shot A LOT of stewarts, from small parts to full planes, new and old alike. He knows what he is doing and he has no idea what went wrong. Pretty much anyone can pick up a 14.00 harbor freight gun and shoot an acceptable finish with polytone. I like the finish of the stewarts, but the application seems to be WAY to picky. I think I will strip down what I just paid 4k to have done and recover and shoot it myself with polytone like I should have done to begin with.

    And yet literally....thousands have had no problems. Could there be a problem with the product? Certainly...but the company would definitely take care of it. Did your buddy contact them and talk to them about a product problem? I don't know of anyone that has any better customer service. But why is it always a problem with the product? I've only used this product for a bit over 25 years and I've screwed it up a few times, trying to shoot it like the solvent borne stuff....but I'm first to admit that! I'd also stand behind my work, if it was screwed up, I would either be redoing it or you wouldn't be shelling out 4 grand!! It's really not that picky for the most part, as long as you follow a few very basic rules.
    Yep, I totally agree that pretty much anyone can shoot polytone and get an acceptable job.... Poly fiber has always been very forgiving of mistakes. But polytone doesn't compare to the Polyurethane finishes either.

    To the OP, if you're having trouble with shipping, Stewarts ships non-hazmat.

    You can have problems with any cover system. When I did the J-3 spar replacement a few years ago I orange peeled the hell out of the top coat of butyrate! I’ve shot Polytone and Butyrate for years with no problem. A quick call to Consolidated got me squared away.

    I am still waiting to see a completed aircraft done with Stewarts top coat that has the gloss and finish of the test panels. With thousands and thousands of them out there you would think there would be one here in San Diego that I could go look at and talk to the painter.

    I am quite sure it can be done - the Stewarts videos show a really beautiful Citabria.

    My buddy left his wing tank on, and now has unsightly blue streaks on the brand new Stewart’s finish. I tried compound - made the paint really shine,but didn’t touch the blue streaks. Any ideas?
