Im using some inexpensive nason acrylic enamel paint, adding flatten-er to it to tone it down "I hope", using some 2 part urethane primer, gonna put it on good and thick in light coats of coarse, to help hide some of the bs, And then I used self etching aerosol cans from the paint supply store.
Today I got the pc 11 marine grade epoxy putty on to help cover up the crappy job that was done lining up the sheet to the existing seat/deck, I had it welded all the way across and got it ground down, then applied the pc 11 like bondo. Hope it work, I imagine I am goona be repairing cracks for the next 3 yrs anyhow due to insufficient material being left were the corners were welded etc.
