Hi, Ana diez! Welcome to FGRV and congratulations on your new-to-you Boler!
Painting fiberglass isn't a lot different from
painting anything else. The better the surface prep, the better the
paint job. You use
paint that matches the surface you're
painting, and primer first.
If you'll go to the
Search above on this page, click and drop down to the lower line and type in "paint Boler" and you should find all kinds of threads to give you a great idea. You can also find videos on YouTube that show you "roll and tip," which is one way to paint these. Others are brush (not necessarily best), spray, and foam hot dog roller alone. (We did the last).
You need to use an enamel paint, NOT latex, not ever. You can mix more than one color of the same type of paint--if you want
light blue, you can mix white and a few drops of a navy blue until it's more what you like. Just don't mix different paints, like latex and enamel. (Hint: it'll still go on, but it'll be very odd.)
We used Rustoleum Marine primer and topcoat, both in white. There is Brightside (or Briteside marine paint, and since most boats today are made of
fiberglass, there you go). There are other brands of fiberglass/marine paint. Always use a compatible primer.
Wash the area first, always sand with a fine grit, and prime. If you find flaws in the surface, you can use "Bondo Hair" or a similar product (can be found at auto supply stores for
fiberglass cars), sand, wash, wipe with acetone, let dry, then prime with fiberglass/marine/auto primer and sand carefully again. Then give a 2nd coat...use THIN coats.
If you want to spray, you'll find threads here and videos on YouTube about that, too. We found Rustoleum to be available locally (it does matter some), reasonably priced (though not cheap!), and satisfactory. In two years, the paint still looks fine after many washings and sitting outside in the sun and rain without a cover. You can also get rubber-type paint for preventing rock chips, but it's tricky and very pricey.
I don't recommend you paint the top half a dark color--too much heat gain in warm weather.
Any specific questions? Do your search and read up...and soon others will be along. We didn't "roll and tip," because Paul found it awkward and leaving streaks...instead, he rolled and rolled until all the itny bubbles were popped and the paint began to self-level. He did two very thin coats of primer over the "fairing" (Bondo Hair nick and small hole filler) and two well-rolled out, thin coats of topside, and sanded well between.
When done painting, you can "wet sand" (see Search again for this idea) for a really ultra smooth effect.
We don't wax "Peanut," our trailer, a 1973
Amerigo, as it's just one more step and so far everything except rock chips has washed off readily with liquid dish detergent and a car washing brush. We've towed thousands of miles now (well, about 2 thousand) and camped many nights.
It's easier and cheaper to read and watch videos than to buy the wrong stuff and repaint it, so do your reading and watching before you decide how to begin.

Our very best to you on this rewarding project and may you have very happy camping!
PS--we love pictures, post some
if you can--before and during and after!
