An experiment with acrylic pourable medium over oil pastel painting

A while back  I  did an oil pastel  painting on a wood board and this tends to remain sticky for a long time.  Now it has cured but it is still crumbs of oil pastel; on it. So I thought it would be a good subject for applying  a clear pouring acrylic medium on it,.  The acrylic medium would seal the surface of the painting and protect it.  

So last summer I set up a space outside to do it.  The first challenge was to set it up outside (the smell of the medium is quite strong) and have the artwork levelled - on the ground over a plastic sheet, not so easy.  As one pours the medium, it spreads over the surface.  If the artwork is not levelled, the thickness of the clear coat will not be uniform.

Before application. Doing it outdoors,  small flies can get into the goo..

During application.It is milky white at first and dries clear

 It really made me think of liquid wax for floors in the old days. It is self-levellling- mind you the surface for the application must be levelled, so one has some control over the thickness of the coat.  

It dries quickly, like in less than 24 hours.

Very easy to apply. It worked great and I like the result. Very modern slick look, and it protects the oil pastel.  i will see how it ages.  It has been a year and I have not noticed see color changes.
