    Hi Folks, I have some mild steel and lead joined with polyester resin that I now need to seperate. Any suggestions on what chemicals I could use to soften or dissolve the polyester resin? I'm thinking Acetone would be the best bet, just wondering if there are any other ideas?

    Don't waste acetone on it, that doesn't work. Paint stripper (very alkaline, NaOH or KOH) will slowly weaken the resin, Frosty's solution works immediately.

    Methylene Chloride and MEK work as well. But fire and heat usually work faster.

    Or use a high speed grinder, or circular saw to cut it off.

    If you use enough heat to plasticize the resin so it can removed, you'll also be melting lead.

    Chemicals are the route to take. Freeze it and beat it with a hammer and chisel.
