Step 7Prepping for paint
So far, you've cut, folded, glued/taped, resined and fiberglassed. If you're here, then you have skills. I'm so proud! :sniff:
So now we need to make your piece look pretty for painting. I'll bet you 100 bucks that the outside of your piece was not smooth after the resin set up. So you're gonna want to sand it down, and thanks to the fiberglass, the piece has the strength to take a good sanding. So here's a little sanding 101. Start by hitting the piece with a coat of primer to highlight the problem areas. You'll want to use medium grit sandpaper with a sanding block. Sand in a circular motion over drips, runs, and anything else that stands out. If you come down to the fiberglass when sanding an area, you might want to stop sanding that spot. Go any further and you'll get a hole. So sand all the areas you can without perforating your piece, aiming to keep it more smooth than flat.
Now wipe/blast all the dust off, mix some resin, and coat the outside again . This will re-coat the exposed fiberglass, and add integrity back to the piece. Once it's cured, prime it. The 2nd resin coat should have fixed most of the irregularities, but if you see problem areas, sand em down. You shouldn't be seeing fiberglass. In case you are, apply bondo to the smaller sanded areas, instead of putting runny resin on it. It's less messier and more direct for smaller areas. But if your piece is still covered in nasty spots, resin it again.

If you're willing to spend a few extra bucks, what I would have added is to apply a layer of Bondo body filler to help get rid of the larger imperfections. Then I would have primed it and sanded it down.
