RE: [RCSE] Removing old covering, more info
Dope based?? could be silk-span.Find yourself a container of dope thinners to start. You will find that any dope-based finish be it silk-span, tissue or silk can be stripped quite easily. The previous post works for the most part. You should be able to soften any stubborn areas with the dope thinners.

RE: [RCSE] Removing old covering, more info
Craig, If it is dope based, then acetone will work fine. However, any color in the dope will probably remain in the wood or seep into the wood. I might try nail polish remover, as it has some MEK, which like acetone, works but is less volatile and may contain some nitromethane. You might try methylene chloride or chloroform. I do not thin isopropyl alcohol will work, but perhaps some mineral spirits. Do remember that if there is any foam, then all this stuff is useless. I have a Friend who works alot with nitrate dope and tissue who I will try to contact for more info. He is a free flighter from 40 years ago!

Skyloft was a nylon mat material that looked a lot like silkspan but was much stronger. It was applied with dope just like silkspan. I used it to cover several RC pattern models between 1969 and 1974 and even covered a free flight wing with skyloft. If you crashed a built up model covered with skyloft, you never needed a trash bag for the parts after a crash. The skyloft served quite well to contain the parts. :) Chuck RCSE-List facilities provided by Model Airplane News.

This is a list of some rather nasty chemicals, i.e. carcinogenic, mutanogenic, or simply poisonous. Please to be careful, wear gloves (not latex) and lots and lots of ventilation.

Re: [RCSE] Removing old covering, more info
Hold on there! Carcinogenic, mutanogenic, poisonous! So, should I be worrying about the times (as a kid) that I used acetone as a hand cleaner to remove things like grease and fiberglass resin? Concerned modelers want to know. Well this one at least. Bill Swingle Janesville, CA RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Removing old covering, more info
That's the least of my problems... Didn't you clean old quarters with mercury? used Acetone, Naphtha, jet fuel, and anything else we could find to clean our hands... and the worst of all... Film cleaner (triclorethane 1,1,1) in a ultrasonic tank. Our old house would probably be put on the Superfund list if they ever tested it :-))) - Original Message From: Bill Swingle [EMAIL PROTECTED] To: Bill Johns [EMAIL PROTECTED]; [EMAIL PROTECTED] Cc: Craig Allen [EMAIL PROTECTED]; soaring@airage.com Sent: Monday, August 18, 2008 3:41:23 PM Subject: Re: [RCSE] Removing old covering, more info Hold on there!

Sheiiish, here we go. I was not referring to acetone. I was pointing at the chlorinated hydrocarbons (methylene chloride or chloroform) and nitromethane. These can be bad actors. Simply because you've used a lot of stuff in the past that we now know is evil and you are still alive doesn't mean it's safe. As chair of the department safety committee I've learned to be anal about certain things. If you smoke tobacco forget everything I've mentioned above, it's already too late. If you don't smoke, have used all those evil chemicals and are still alive, don't think you're getting off free. Do you still have all your hair? Do you hit every one of your landings? Can you sleep 12 hours without having to get up to pee? If you can't answer YES to each of those questions, all those chemicals are getting to you! So There!!! ;-) Cheers, Bill RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Removing old covering, more info
What worked for me was a combination of sanding/buffing discs on a Dremel tool. Friction did cause some monokote color to meld into the surface of the wood, but I was using opaque for the refinish, so it didn't matter in my case. Instead of caustic chems, I have a theory: consider a heavy glove and a chunk of dry ice from the local ice cream shop or megamart. Try rubbing the chunk of dry ice on the edges of the covering. In theory, it should cause the mylar and glue to contract, embrittle, and crack off, the wood should shrug it off, and the glue joints will likely hold if not directly touched.
