Do yourself a favor and get some of EC's Coating Resin... maybe some of the black "basecoat" resin ..
If you count on only applying one layer of CF, then the white background will be clearly visible through the CF.
Sand down the plastic lightly, degrease thoroughly, then apply black "basecoat" ... follow the procedures in the EC "skinning" video on "the toob" or from the EC website.
Since this is a marine appication, finish off with marine varnish. (For UV protection)
Good luck ...
