ProSeal is still what is used most often in aerospace, there was a 3M epoxy called metalset, which was light green color that we used to bond nonstructural aluminum pieces together on the Apache, and was also used to bond the skin to the spars and leading / trailing edges of the main rotor blades. all of these applications were dry. As messy and smelly as ProSeal is, it's very good at sealing aluminum. We were required to use ProSeal on all electrically "bonded" joints on the Apache. All grounding studs etc. received ProSeal after testing for electrical "bond". You can imagine how much "fun" it was trying to avoid this stuff while working on the transmission deck or cockpits!

I would think that by now there are better bonding agents for aluminum out there where one could possible just glue aluminum panels together instead of riveting. Anybody heard of anything like that? I am about ready to cut aluminum for making my tanks and am still debating welding, riveting and proseal, or any "new" options that I have not heard of. _______________________________________________ see KRnet list details at http://www.krnet.org/instructions.html Scott Cable KR-2S # 735 Linden, MI s2cab...@yahoo.com --------------------------------- Do you Yahoo!?
