I'm in the painting process on my build. I have 2 coats of exterior flat latex thinned about 10% as the base coat. I sanded with 120 grit between coats and after the 2nd coat. The canvas came out surprisingly smooth. I put the 1st top coat on yesterday (Sherwin Williams Exterior Satin in gray). I let it dry overnight and hit it this am with 320 grit (because I'm out of 120 and 220) and holy cow was it smooth. I just put the second coat on. I'm wondering how many coats is enough & how many are too much (is there such a thing)?
