Yep. Does it every time, even with VHT's high heat clear. I like the Duplicolor aluminum stuff. Wipe off any stains, touch it up if ya need to. Easy to keep nice.
Boy, one little drip on raw aluminum and you're screwed. I've never found anything to really clean it good.
Years ago I had a little red drip from Loctite It bugged me so bad I finally took a die grinder to it.:elmer:
