        Hi,

        I have an old cast iron sink that I would like to strip, paint artwork on and seal with some type of clear coat so the sink can still be used. As enamel will react with acrylic paint, what type of clear coat would you suggest that will be strong for regular use on a sink? I am not comfortable with oil pigments. How would enamel clear coat work with water color or gouache pigments?

        Suggestions?

        Thanks in advance,
        Shad

        Welcome Shad!
        I do not know the answer to your question, if you’d treat it as ceramic and bake color on or use acrylic. Just a wild guess if it were my sink I’d probably use spray paint. I’ve sprayed antique creamer stands before that are cast iron, did not put a finish on, and put outside for years with minimal wear and tear.
        Enamel clear coat would cover the watermedia but not sure how durable the paint film would be.

            Thanks for all of that detail! I will have to give this some further thought and may just have to test it out. At most, I could just sand it off and start over. All part of the learning process, but the digital world and CTRL+Z has spoiled me. :lol:

            A few years back I painted a mural on a Cherry wood coffee table, then used flat black spray paint on the legs. I used Krylon’s enamel clear coat and the chemical reaction between the enamel and acrylic paint instantly cause the black acrylic to crinkle and peel right off the wood. I was shocked!! It worked as a perfect instant-result paint stripper! yikes! So I called Krylon and they said enamel over acrylic will do that. :/ (I know this story is getting long, but perhaps it will help out someone down the road, so Reader, please bear with me.) Sometime after that lesson, I found a video tutorial how to paint a skate board with spray can acrylic and clear coat it with spray can enamel … Essentially the same thing I had done, but just successfully. His trick was to do fine coats of enamel and many of them. I wonder if I could find those videos again, because there may have been wet-sanding between coats as well. I may have just answered my question. Haha

            Thanks again!

            Right! I’ve used spray paint and the coating for years, different projects, and has held up well.
