I know this to be especially true for the 'PSTF' range of dyes, but I imagine they will all be similar products and hence it could be a common concern. In the testing I have done, it seems to effect certain colours more than others. It obviously also isn't going to happen over night, and it does depend on UV exposure levels, but it is worth being aware of. Mat, I can't speak specifically for GlassCast as I can't get it here, but I use a product called Kraft Kote which is also a self-levelling top coating epoxy, and so should be very similar in their chemistry. I use this all the time over the top of acrylics and enamels, and it works perfectly. Here is a workbench I made, where my logo is sprayed using an acrylic: \ Thanks Hanaldo, either way I was going to try it with acrylic as a base of the to be coated project but knowing it is possible makes me a bit more confident now...will give it a try and share my experience Matthieu Libeert Founder MAT2 Composites X Sports website: www.mat2composites.com

We do a range of Epoxy compatible pigments for solid opaque colours as well as 10 different tinting pigments. However there is a wider range out there in the art and craft side of the market including more colours, metal flakes etc. Most of them will be fine with epoxy, however it is always worth asking the question of the pigment manufacturer and if you are really unsure then its worth doing a small test piece to see how it comes out.
