The masking fluid saved the orange dots in the water when I painted blue and gray on top of the masking fluid on top of the orange tint.
When the paint was dry I scratched off the bumps of paint on top of masking fluid with my fingernail. After I do the dishes my fingernail will be ok but there’s some paint discoloring it. That’s a normal fingernail for an artist. If you try this maybe you will think of a better way to do it than scraping with your fingernail.
People say masking fluid doesn’t work on oil paint. They are misinformed. If I can make it work, you can do it. I’ll give you the tips.
First, tint the paper or canvas with a thin wash in the color you want to save with masking fluid. They will tell you masking fluid doesn’t stick to oil paint but if you thin the paint enough with terpenoid you break down the oil and when it dries the pigments have less binding them to the paper and they get a little powdery. I brush off dry loose pigments with a paper towel before painting the masking fluid on it. The bright orange left plenty of color.
Second step, paint the masking fluid on the dry oil paint tint.
Third step, use a deer foot brush to put paint on top of the masking fluid without lifting it. If you use a stiff brush it might make the masking fluid come off but this brush which works great for stenciling won’t lift your masking fluid. You can build up a few layers of glazes and still see where the masking fluid makes bumps under your colors.
When it’s dry scrape off the bumps and Voila! masking fluid saved your bright dots or lines! This is easier than trying to paint bright orange dots on top of the blue and gray glazes because the orange is a semi transparent color and it shows up bright on a plain white paper or canvas but if you want to have bright orange dots on top of the blues and grays you have to take the time to under paint the dots with white and wait for the white to dry then do the orange on white.
So, yeah, if someone tells me it won’t work I might try to do it anyway. I learn the hard way sometimes but I’m not afraid of failure and once in a while something works for me and others don’t try at all. I could say I’m hard headed like my Mom or I could be a skeptic like my Dad or an unholy mix of the two. hahahahah
