I'm curious if anyone out there is using acrylics for their filtering process? I have had success with oils and enamels, but have such a greater variation in colors with my acrylic stock. If you are, are there any special techniques used? What do you use to thin the paint? Water?
Looking forward to hearing from anyone!
When it comes to weathering, I think anything is fair game! When I need a dead-flat and quick drying effect, I never hesitate to pull Vallejo colors off the shelf. I think the key is, whether you are using them as filters, washes or whatever, is in the consistency. I always reduce mine with distilled water and a tiny drop (probably no more than a half-brushful) of Vallejo thinner, and make sure the mixture is stirred completely. The thinner acts as a binder while still allowing the pigments to float freely (if that makes sense?).
Vallejo has such a fine pigment that it will dry almost as smoothly and completely as oils, and you can easily make them nearly transparent to leave just a hint of the color behind. Also, I freely mix Model Color and Model Air to create about any shade I can dream up!
It might take a little experimentation to understand the potential, but I've been using Vallejo as a glaze on tanks and figures for several years with very cool results.
