    Angry Oops!

    I screwed up, but luckily not on a weld. I undermixed the hardner in some body filler, 2nd pass, and now have a mess. I scraped up what I could, but don't want to put down another coat until I'm sure it's all off, don't want to end up with uncured filler under my paint. Sanding resulted in a bigger mess.
    What can remove the uncured filler?

    Unless you really went low, the stuff should eventually cure. Some of the fiberglass surface curing agents might work too. The filler you used was polyester right?

    A Stanley shur-form file or as some call them a micro plane should get it off, of course you'll get some of the first coat as well but you'll be sure to get it all off. Most of the time though if it's just a little bit the next coat if mixed properly will cure what little remains. You can also use the surface hardner for fiberglass as mentioned before.

    It's been on there for 2 days, still soft. Yes, polyester, Marstons

    Not enough on there for a surform file, total thickness is less than 1/16".

    1/16" is pretty thin. Try the surface hardener and maybe a little heat from a hair dryer or heat gun (just don't go too crazy).
