Uitekai If you go to any big art store(I stick with Hobby Lobby), You should be able to find Fixative, it's for Graphite, Pastels and charcoal. It works really well, especially the the workable kind that lets your preserve and then work right over the top again without smudging or ruining. The price is only about $5-7 per can. Just ask a store employee about it. i was under the impression that spray fixative only worked for chalk pastels. i mean, wouldn't putting something liquid onto oil pastels just worsen the smudging?

Found this today: http://johnelliot.com/ques.htm I am concluding my first attempt with oil pastels and have found that I am very pleased with the work. Having used light weight paper and a lesser quality oil pastel, I am concerned that the work will degrade quickly. In this case, would you recommend a fixative? Intrinsically impermanent materials will not be made more permanent with fixative – there is no magic wand that will make degradable materials into archivally permanent materials. Your best strategy is to paint any new paintings with archival professional artist quality materials. As for the painting you have already done, my advice is to carefully frame it, keep it out of strong light and excessive changes of temperature or humidity, and enjoy its beauty before it ultimately degrades. Do I need to fix or varnish my completed oil pastel painting? I don’t fix my completed oil pastel paintings for two reasons: 1. The nature of the oil pastel medium is to be self-fixing. It is not dusty or loose on the surface – I feel there is simply no need to fix something that is already “fixed” in place. 2. Fixative changes the color of the oil pastel. (see color swatch below) HK Holbein specifically does NOT recommend the use of fixatives over oil pastel. See their advertisement in Jan-Feb 2002 Pastel Journal page 58. Sennelier has recently developed a special fixative for oil pastel. I plan to experiment with this for special effects, limiting its use for small areas of underpainting. I do not varnish my oil pastel paintings for archival reasons. Unlike oil paint, which dries with a hard skin, oil pastel never completely dries but just hardens somewhat over time. To apply a varnish over something that is still workable does not seem prudent as a materials handling strategy. Further, as you may know, an old yellowed varnish layer on an oil painting can be removed by a conservator and a fresh new layer applied because the oil paint has created an impermeable skin in the drying process. I am not aware of any safe way to remove an old yellowed varnish layer from an Oil Pastel painting, since the oil pastel underneath would never dry with a protective skin. As with fixative, varnish also changes the colors of the oil pastel.

that is amazing, Euclid. i never would have considered that even varnish messes up the colors of oil pastels.

Hm.
I recently used fixative on an oil pastel drawing, it didn't worsen enything really. Despite the fact that I used a matte finish (workable)fixative it was shiny, but otherwise you can't smear anything on the picture.
It worked fine, I think.

It worked fine, I think. yeah, i was just guessing earlier confused . what Eulclid posted says is that over time it will worsen, but my guess (comparing this to drawings i have which i haven't bothered to do anything to sustain), is that it will take about a year or more to really show a dulling of color and such. but i don't really use oil pastels, so i don't really know how long it would take.

*shrug* I just went and googled some info on oil pastels and that's what I got. Sounded like the guy had some experience with oil pastels, much more than I do, anyway. xd
