Hi Zor. Good to see ya.

I like to use thinned epoxy. Mix slow epoxy one part A, one part B and 1 part 90 percent isopropyl or denatured alcohol. Brush on in glops and squeegee out thin with a card. When dry, sand or I like to lightly scrape all over with a single edge razor blade held near 90 degrees. Go until all the high shiny areas are gone and you have a smooth sort of burnished finish.

Fills pores and adds strength.
