  1. Thank you so much for this email. Just today I had a question for my teacher regarding gesso.
    I have been having a problem with my oil paint looking like its just soaking threw the canvas. I used 3-4
    Coats of gesso. I am going to try the GAC100 then with theGAC200 its worth the try!
    Thank you again for emails, I appreciate them so very much.

  2. Dear Greg, is it necessary to varnish very thick oil paint from a conservation view point? I understand varnish protects paint from uv light, dirt, and gives an aesthetic appeal. But could it be more problematic as very thick paint can take quite a few years to dry? Kind regards Sam

    • Hi Sam,
      It is always recommended to wait until an oil layer is “hard dry” before varnishing. That is, any impasto applications are hard throughout and do not dent with pressure from a fingernail. If a thick application is still soft in the middle, then it should be allowed to dry longer before applying the varnish. Beyond that, varnishing is always an aesthetic decision as much as it is about longevity. Varnish can change the look of a painting, especially when there are thick and thin areas and variable sheen throughout the work.
      We hope this helps!
      Greg
