Hi all,
I bought some AK Interactive Gravel and Sand Fixer lately and did experiment a bit with this product.
You'll find a detailed review with lots of pictures on my blog.
My conclusion:
The AK Interactive Gravel and Sand Fixer is a good product that is not a must buy, but comes in very handy when a matt, natural finish is important and a convenient product, that does not require premixing, is required. The ability to topcoat pieces with an airbrush is an added bonus.
The main advantage lies in the properties of the fixer, that is being absorbed quickly in the sand and fixing it in its current shape. While this is possible with PVA, it is more tedious and requires much more time.
I would thus recommend the fixer to people who work a lot with dry pigments, soils and sand, where preserving the colour and texture is important. At 14.99 NZ Dollars the product is cheap enough to give it a go and I think you won't regret it.
Here a picture of the dune I made using the fixer:
I am not entirely happy with the shape of the lines, but will experiment more and hopefully achieve a look that resembles more the archetypical dunes I have in mind.
I went for a Barchan dune to keep it simple for starters.
