Hey all, I recently seen some responses mentioning Sig Koverall. I am using a foam wing on a home build that needs to be covered. Would Koverall work well for this type of application. My friend already used monokote on his and it came out really sturdy. I checked out Sig's website, but it didn't say much on how you apply it. I live < 30 miles from the Sig plant, so pickup is an option that I am considering (along with an LT-40 ARF). Thanks for all the help.

I’m one of the users that has posted several times regarding Koverall. I use it for all my airplanes but I use it over conventional built up structure where I believe it excels. For covering a foam wing I believe I would stick to monokote. Koverall requires sealing and finishing with dope and it would melt the foam. It might be possible to seal the foam with white glue, then apply Koverall over that but now you’re adding unnecessary weight and work. Also when Koverall shrinks, it exerts a lot of force and that may warp a foam wing. As well as I like Koverall, covering foam wings would not be a good application for it.

Thanks lou for that insight. It will help a lot on that, but are thier directions on the web for doing this? I am interested in doing a kit later where I will need to cover it.

I don’t know a site that goes into detail on covering procedures. Sig’s instructions assume that you have some basic experience in covering and are pretty sketchy. When you get ready to build something, drop me an e-mail and I will be glad to go through the procedure with you in as much detail as necessary. Bear in mind that bare fabric covering, such as Koverall, requires the use of aircraft dope for finishing. If you must build in an apartment or on the kitchen table, the iron on plastic coverings like monokote are the way to go. However if you build in a place where the odor of dope is no problem, It produces a much tougher, and I think better looking, finish.

I will certainly look you up when I get ready to cover. I fixed the issue of the odor by moving th kitchen table to the garage (we got a new table for the kitchen).

You could try to cover with fiberglass . It is relitivly easy no smell on dope . but you still have to paint it .
