    Does anybody know what alloy of lead the factory used? Period correct (1970), auto body use type would be appreciated also. I am pretty much limited to pure lead or 50/50 lead/tin. The latter of which I would prefer to use. I am cleaning up the dutchmans panel on my 1970 Newport convertible which was leaded (hastily) at the factory, then bondoed. I just want whatever I put on to get along with whatever they put on. I am also wondering if flux was used? WP_20170806_19_22_55_Pro.jpg

    Eastwood has 30/70 body lead. Body Soldering Sticks 10 pack

    Yes, it would be tinned at the factory.

    Leading is an art... Not easily learned. I tried doing it once a long time ago and it's a matter of doing a lot of it before you can get good at it. I never did.

    I'm not a body man, and someone else can chime in here, but I think you'll find that modern materials will do a better job.

    Thanks Big_John, I didn't know they offered that. I am not expecting a perfect "no bondo" finish. Simply looking to seal the base with real metal, then a skim of "all metal", followed by bondo. This could have been avoided had the factory guy been more liberal in the application of lead, in the photo I posted you can make our the "T" intersection where the dutchman meets the quarter and trunk rail. This is where moisture was able to compromise the talc in the bondo. I am trying to avoid that in another 47 years.

    I'm being cereal! Come on! I'm "only" 36, so mathematically it is possible. Winking smiley face.

    Yes you need flux or tinning fluid. Sand blasting the area first helps also. I have never done lead work in the area you want to do it but have soldered a few gas tanks and it take some patience. Like Big_John said it's a art one I haven't mastered yet
