i found a not so nice rust hole in the quarter panel of my GMC Jimmy last week. i have been thinking about how i want to tackle this job, and the thought of taking a small piece of steel, then tinning it with lead before attaching it to the inside of the panel occurred to me. it should be rust proof because of the lead coating. which would make it a "permanent" repair. well, at least until the rest of the panel rots away. i tried tinning a piece today, which did not work so well. then i appied soldering flux to it, which helped, but still had some spots. then i got out the acid flux, which worked beautifully. the question now is, what to do with the rest of the lead in the pot. i fluxed it twice with parafin, and twice more with saw dust. then i poured all of it into ingots, so i could thoroughly clean out the pot. i have no idea if it would be safe to use this lead for boolits or not. if any acid is left in it, it could seriously corrode a nice barrel. and lead is not anywhere near as expensive as barrels (thankfully). any idea how i could check to see if there is any acid left in the lead? i would not like to throw away 20 pounds of lead if i do not have to. but i would rather do that than ruin a barrel.
