    Just a quick question. When I'm done welding on anything with my wire feed it looks like there is rust on it. My welds look good it just looks like there's rust on them. Am I doing something or not cleaning enough or something?

    Did you wire brush them after? Should come right off.

    How long after are you talking about. . .immediately after or days after?

    If it's immediately after then it's silicone (IIRC. . .it's been a while since I was in welding school, but I asked about this at the time and I'm pretty sure that's what I was told) and it will wire brush right off.

    Silicon. Silicone is for caulking your bathtub.

    So wire brush it and then silicone them? You mean the spray silicone lubricant stuff?

    No, the brown stuff is silicon. . .just wire brush the silicon off and you will be fine (you're fine without wire brushing the silicon off, but your welds will look prettier without the little brown spots on them).

    Ok on to my next question. What should I put on my chassis if I'm not going to paint to keep it from rusting. I see lots of trucks with bare metal and no rust????? Thanks for the help guys.

    WD-40 seems to be pretty popular on here. . .

    i like lanolin spray. You can get crap loads of it and its non toxic. Just have to put up with your rig smellin like sheep! If your from New Zeland that is a turn on lol.

    I use floor wax paste, like hardwood floors, seals the steel and doesn't stop you from welding.

    Its silica slag (like glass), a by product of the welding process. Wire brush it off and it should be ok.
