I'm in the process of removing and replacing the inner skins in both fuel tanks on my Cozy IV.

See http://forum.canardaviation.com/showthread.php?t=4594 for a detailed report and pictures. I'll post more pictures on my web site when the repair job is complete.

Chris Barber - we need to buy each other a beer :)
