  8. Re: My Heico Perma Wash Does Not Smell...Is This OK?

    Since probably around 1980?, my stock bottles of HEICO PermaWash always had a faint sweet "plastic" smell to them. Never even after use did the liquid have anything close to a "fixer-ish" smell to it.

    Educated guess is that it's a single Meniscus with the front open "aperture" being the iris. Can you read the "No" # and the patent year?
