As long as the material has no oil in it, it's safe for vinyl.
Personally, I prefer soft body artist acrylics. It makes a huge difference. I started off with those cheap acrylics you can get for under $1 per bottle and they gave me nothing but trouble. I thin the acrylics with a mixture of flow improver and water, so I can get smoother, cleaner lines. Regular water is fine, but I find that the flow improver makes thinning easier.
