We cleaned the plastic using Marine Clean from POR15, then sanded with 220 sandpaper, then blew off the dust with compressor, then wiped it down with Xylene (recommended for TileDoc). After that, used a cheap sprayer to spray on the paint. The first coat, I put it on too thick and it ran in some places so I had to wipe it off and try again. Also, make sure all soap residue is sanded/cleaned off well or the epoxy won't stick and will bead around it. I had a spot in the sink basin I had to sand a second time to get it off.
