you can also spray with gellcoat, then PVR over the top. the PVR seals the air off so the Gellcoat will kick.
all of these methods leave a thin coat, which is great if you are dimensions are very close to final. My problem is when I am building something new, I often have to take 1/8 to 1/2 inch off to make the body right, which means I need to eat into the glass.
And for that, I sand down past where I want, then skim it with bondo, lots of elbow grease with sandpaper to make it smooth, then paint over it.
Most of this to make the plug of course as once you have a final product, you can make a mold and from then on the bondo is needed a lot less.
