Okay, folks, it looks like the demands are for paint and bunks!
If you look at the existing pictures you can see the paint job. The wide dark red stripe wraps around the front and two sides of the fiberglass body following the body's natural lines -- the seam between the top and bottom, and the rolled-under edge that supports the seats on the inside. Of course, you can put your paint wherever you want. This just happened to fit really nicely with my two-tone Bronco's color scheme.
How To Do It: If you've never used automotive paint and a real body-shop style spray gun, and you don't have a properly-vented shop area and an appropriate breathing mask, take it to a body shop to have it done. WARNING! The materials used in automotive paint are poisonous if breathed!
If You're Still Interested: Go to a local auto parts store and buy a couple of sheets of 220-grit wet/dry sandpaper, a quart of automotive paint, a gallon of reducer (thinner), and a set of fresh filters for your breathing mask, and anything else they say you need (like "hardener", etc.)
From here on, everything should be accomplished in a single day! Wash the trailer with a good car-wash detergent. If there's any mildew, kill it with Clorox. Rinse thoroughly and let dry. Then go over the surface where the paint will be applied with a clean rag soaked lightly in the reducer you bought. You shouldn't need more than a cup of reducer to do the whole trailer. Turn the rag frequently. Let it dry again.
Mask out the areas where the paint will not be applied. Cover clear to the bottom and top of the body so that "overspray" won't settle where you don't want it. A body-shop-style masker with a roll of two-foot paper makes this go faster. You can use newspaper if you carefully tape ALL seams shut.
Once masked, use a folded sheet of 220-grit wet/dry sandpaper with moderate pressure in a circular motion about the size of your hand and go over the entire exposed surface. Be careful not to damage the masking tape. Once this is finished, wipe it all down with another clean rag with reducer and let it dry. Now it's ready to paint.
Mix the paint according to the manufacturer's instructions for your type of spray gun and your temperature and humidity conditions. (I'll assume that you have a spray gun and a clean, dry supply of compressed air. If your air hose has been used on an unfiltered compressor, it probably has oil in it that will mix with the paint at the spray nozzle, and make your paint job do strange and horrible things! If your system doesn't have an oil/water filter, it's not the kind that should be used for this. Go to a body shop.) Put the properly-thinned paint in the cup, assemble the spray gun, and put on your breathing mask.
Unless your shop has a ventilation system that can make a noticeable breeze inside it, I'll recommend that you do the painting
outside. DO NOT do it in a closed shop without ventilation. The fumes can make you VERY ILL, and some effects can be permanent! I can't emphasize this enough!! So... assuming your fully-prepped trailer is out on the driveway and there's only a LIGHT
breeze blowing (and your prized 1954 Cadillac is far, far away), connect the spray gun to the air hose and go have fun. The hard work is done!
I used DuPont products. It's been on there long enough that one side of it has water marks from being watered by the garden sprinkler for several years, and it shows absolutely no signs of peeling or cracking. If you know how to use body putty and have flaws in the surface, have at it. If a bug settles in your freshly-sprayed paint (because you're painting
outside), well... don't try to remove him while the paint's still wet! Let it dry, then pick him out and use some touch-up paint applied with a fingernail polish brush. It's a good idea to wait for a warm spring day before the bugs hatch out, or a warm fall
day after a hard freeze to kill the bugs! (Yes, you might have to wait six months for the right "window of opportunity".)
If there's anything here you don't understand, just post your questions here for everyone's benefit.
I'll have to take some pictures of the bunk, but will post them with instructions soon. Happy painting!
