Slow drying time can be a problem for artists such as my self who like to sell their paintings so my next adventure into this medium is to us a product that will speed up the drying process.
My main intention in using WSO's is to allow myself more "plein air" painting time as in Florida & the Southwest acrylics dry almost too quickly - certainly within one hour of being applied.
The acrylics I use ( Chroma Interactive ) dry (cure) slower than most others on the market but in the heat they still dry too quickly in a plein air environment.
