I just tore the ratty 20 year old solid color Monocoat off my 30 year old Magician to re-cover it for the 3rd time and the leadouts were VERY VERY RUSTY inside the wing. To the point where their strength was clearly compromised. The portion of wire extending out the tip was fine...I'm guessing due to fairly constant exposure to oil residue.

Its going to need some surgery as well as new covering.

I'm thinking I'll wipe down the new leadouts with acetone and paint'em with Rustoleum before fishing them back in.

UPDATE: pic of rebuilt Magician with new silk covering, new cloth hinges, beefed up spar, new leadouts, and fresh paint. Ready for another 20 or 30 years ;->
