    So, I stopped by a local electrical supplier today, and mentioned my quest trying to find Scotchkote. No local source carried it anymore and any time I tried to order it online, the order process would break. The buy behind the counter noted that was odd because his stock disappeared a while ago and it hadn't been restocked. He asked the owner who informed me that he received a letter from 3M stating that Scotchkote contains a chemical that is now illegal to sell in or ship to Ohio. :(
    I anyone else running into a similar situation?
    What are some other proven ways to waterproof receivers and servos that people have found?

    Hi
    This is a bit offtopic and yet quite relevant
    in Denmark we have a small group of people who try to build a manned space rocket - http://www.copenhagensuborbitals.com/. They have a specialist with them who are constructing all their electronics. I have met him once and know he has a lot of experience with rc - http://webx.dk/rc/rc.htm.
    The rocket is launched at sea and is expected to land at sea. To protect the electronics from the saltwater he is coating the electronics with paraffin or "kerosene" - http://en.wikipedia.org/wiki/Paraffin. He can make repairs to the electronics by removing the paraffin with a heat gun (not too much heat I guess, that would blow away the components as well). I guess any remains can be removed by flushing in benzene or something similar.
    best regards

    I used it on my nimh packs and was satisfied with its coverage. When it dried it shrunk/conformed and seemed to hold well. I will find out how well it worked when I take the pack apart later.

    I have a cruiser that had this used to seal the wire joints and it seemed to work. I am not going to seal electronics with it althought MG said it would work, I am going to use acrylic instead.

    Markus,

    The parifin is a good idea, but I'm afraid it would not work for area where the temperatures get too hot. A boat running in the sun and temps above 30° Celsius and motors giving off heat would probably get it hot enough to melt.
