So, methinks Spectrafix takes some experimenting, that's for sure............and is not a magical solution for everything...........

This begs the question.....WHY put down a pastel base colour before painting? You can never use a fix like varnish, to give you a perfectly dust-free surface, and you will fill up the tooth of the paper, even tho the fix will give yuo a bit more tooth back, it may not be enough.....so why not find another way of colouring the paper....if that is what you are determined to do? Deborah's suggestion of using gouache is a good one, because its matt finish is chalky and accepts pastels well. Kitty Wallis uses Createx Pure Pigments, which are waterbased. Watercolours are another option. I would not use acrylics because they are, essentially, plastic and used too heavily will clog the paper tooth and give you a slick surface, not good at all. You can use oil paint, thinned with plenty of turps to give you a runny wash. And I know there are stacks of posts here about the use of an alcohol-over-pastel thing. My choice would be inks or gouache or watercolour.
However, there are so many wonderful coloured surfaces around, both paper, and boards, which give you a great start. Unless you are sitting there with reams of white surface which you want to colour, there is really no need to give yourself a hard time by creating a surface which is then difficult to work on without smudging it!
