Has anyone tried Krylon clear glaze over completely dried oil paintings? What kind of clear coat would you recomend?

    KarenKEY Do you mean the clear spray enamel? Probably be fine for a number of years, but I wouldn't be able to vouch for its archival qualities over a long stretch of time without someone having done that 100 years ago.

    I'm guessing, but a coat of clear polyurethane is a better choice if you want to avoid varnish. I would think a conservator could remove it more easily if needed.

        Never put poly anything over your oil paintings. There is "re-touching" varnish that will seal it against dust while it dries and still let you touch up if the need arises.. There are final varnishes in spray bombs that will not react with the oil paint. But, for roughly the same price, there are conservation grade varnishes that can easily be removed and have been tested not to yellow for 100 years.

        This is awesome post about the entire subject

        wybnormal thank you very much! You helped a lot with chemistry behind varnishes! I need to remove varnish and with this article you added that missing piece of info I was after! Thank you!

            wybnormal Well of course don't use poly. I meant it as "harm mitigation" over spray acrylic. 😁 If, that is, OP was set on a non-varnish finish. Based on its ease of removability. My guess is it would eventually peel anyway, in sheets, as I doubt very much it really sticks to oil.

            Better than a non-traditional, polymer-based finish is none at all.
