    I've been using Multi-Etch for a while with my anodizing. I have a tiny batch in a tupperware container (where the batch is just deep enough to comfortably cover a knife scale) that I nuke in my microwave for about a minute, followed by dipping my part. (I re-use the batch for a while.) Despite what everyone says, I find that hot multi-etch, just like Whink, can very easily mar a finish -- especially if it's a shiny or semi-shiny finish. I try to dip my part in Multi-Etch briefly, but no matter what I do, the Multi-Etch keeps ruining the semi-shiny finish.

    Not ruining the finish is supposed to be Multi-Etch's claim to fame. Anyone else have this issue? My Multi-Etch, by the way, is fairly hot -- around 170F - 185F.
