I recently used a glaze (manufactured by a name-brand reputable artist paint & supply company) that you mix, dissolving crystals in solution. But it beaded up on my oil painting like water on a Simonized car hood! I had painted the picture using high quality oil paints, and let it dry for six months.
The glaze would not adhere to the painting surface until I rubbed it on, let it dry, and applied more, never achieving a uniform finish.
Has this happened to anybody else? What to do!!
I'm not sure what you mean by using a glaze on a finished painting. Glazes are traditionally transparent paint applied thinly, by the use of medium, to create variances in colour & value, enhancing the work through it's effects.
If you're looking for a uniform finish on a dry oil painting, then you should be using a varnish, like dammar varnish, which comes either in the crystals or in liquid form, to be brushed on. Varnishing can be tricky... try googling "Varnishing oil paintings". Lots of info & videos out there to help you out.

Sorry, I misspoke; I meant "varnishing". I will re-post.
