I started calling around to find out if I can have my trailer bed sand
blasted and painted. I finally found someone who spoke to me for a few
minutes. He said that "sandblasting creates toxic waste" and that it
is really not worth doing it any more. (!) He said, just scrape off
whatever you can, maybe use a brush on a grinder in the privacy of
your garage, and paint over it.
The outside of the bed, basically, does not have much rust on it,
maybe one or two spots.
I have a couple of choices. One is just to keep the existing paint and
do nothing. I would, however, like to paint it grey to match the color
of my truck.
Now, if I wanted to paint over existing paint, what would you
recommend for primer and paint. Thanks.
Geez, it's a trailer!
Go find some cheap automotive acrylic enamel, and appropriate primer,
and shoot it with a cheap HVLP gun.
Most auto paint places will have paint that is mixed wrong on their
bargain bin. It's cheap
If utility is more important than color and gloss, don't remove sound
good paint. Just clean it well with solvent, maybe scuff it up a bit
with wetordry paper or Scotchbrite. A 2-part epoxy primer will give
best adhesion and toughness and needs no topcoat, is available in gray
and black (which could be mixed for desired shade of gray) but it is
pricey stuff. Lacquer-based automotive primers are cheap and work
fine on most finishes except Rust-Oleum, then follow with acrylic
enamel for color. Nothing works well on or under Rust-Oleum except
Rust-Oleum and even then it doesn't work very well.
I buy good quality alkyd enamel paints at yard sales for projects like
this and just brush them on. It really doesn't take that long and you
can get it all on without overspray and excesssive cleanup.
I painted a 66 Oldsmobile station wagon with a roller once and yes, it
was a little bumpy it never rusted out and was all one color.
There are so many paints and primers available, it's just a matter of
choosing what's best for you in as far as safety, expense, durability and
You shouldn't sand the original military paint unless you know that it's
safe to. That may be why the one sandblaster said blsting would produce
toxic contamination (of his site, I assume).
Sandblasting to remove paint is overkill. It consumes large amounts of
electrical energy, and usually doesn't serve any useful purpose. The best
use of sandblasting is to treat rusted areas, since the blasting effect is
often completely neccessary for removing rust from pitted areas. The blasted
area will need to be cleaned and primered immediately to protect the bare
Most loose rust can be removed by scraping and wire brushing, leaving only a
small amount of actual rust to be removed by sandblasting. Applying a
diluted solution of phosphoric acid will help remove the rust while wire
brushing. A convenient method to apply the phosphoric solution is with a
trigger spray bottle.
There are additives that can be added to paints to attain good adhesion,
when applying new paint over existing paint (essentially using the existing
paint as a primer coat). One I remember hearing about is named Emulsibond,
or something similar, used for commercial/industrial coatings.
The existing paint will need to be clean before applying any coating over
it, and there are many solvents specifically formulated to clean painted
surfaces. These are generally referred to as prep wash, prep clean or
similar term. The basic solvent used in body shops is a good grade of wax
and grease remover, containg naptha and other solvents.
For more information about preparation and refinishing techniques and
products, see if you can get a refinishing guide from a paint dealer or
distributor, instead of asking sales/stock people at home improvement
Actually..based on the pictures..the camo job is rather cool looking.
Personally..Id keep it.

Since about yesterday, I also think that yes, I would try to pick
paints that match the camo colors. I have yet to make a nice daytime
picture of this completed trailer, the camo colors look really
great. And the bed is nicely shaped, like a good looking 20 year old
girl. If I can find a US flag pattern for spray painting, I would
paint a flag on this trailer also.
Well, yes, except that I could not find flag patterns anywhere. You
know, the templates that you stick to what you want to paint and spray
them or paint with a brush. I guess it would be a set of three
patterns, for blue, red and white paint or some such. I cannot paint
worth a damn, so I would need a pattern.
These stickers work well on gloss paint not on satin or flat. I have
many years experience in this field. If your finish is flat You might
get them to hold on long enough that you can clear coat over them and
seal down the edges but you must make sure the coating is compatible
with the ink used to create the design. Usually it is a vinyl or UV ink
on a vinyl substrate.
Never heard of making a template? Gee I thought you were resourceful.
The reason why most shops won't touch it is due to the high lead content
in the military paint. It can be nasty stuff if you don't have the
proper gear. Normally you would use a water/sand blaster. The water
keeps the dust from becoming a problem. The average homeowner could use
a blaster with a water mist to do the same thing.
Get the three colors of FLAT paint you need at a good body supply shop,
along with a quart or so of gray primer, a couple rolls of fine line
masking tape, some scuff pads and reducer and whatever you don't have
already. Grab a couple rolls of masking paper (or buy a couple rolls of
craft paper from Wal~Mart).
Wash and wipe down the trailer (use a good wax and grease remover where
you intend to put the flags)
Find a picture of a flag that you like. Buy one of those cheap enlarging
projectors they sell and put the flag picture on it and aim it at your
trailer. Mask the entire side of the trailer and then cut out the
masking to leave ONE hole for the entire flag. Make the hole just a bit
over sized so you can use one strip of tape to fill back to the outline
of the flag.
Do that on both sides (or where you want the flags).
Now use a scrub pad to rough up the paint over the entire flag area.
Wipe it down and let it dry while you get the primer ready. Shoot the
primer on so that it becomes a uniform gray color. While it is flashing
off you can get the white ready to spray. About three light coats of
white should do the job. Let that dry for whatever the paint your using
says for masking. Once it is dry enough you can mask the RED stripes and
mask off the entire star field. Shoot the red stripes. Let that dry
and then you can peel and mask the star field. you MIGHT be able to find
star shaped stickers to use for that at a craft store. Mask off
everything but the field and shoot the blue. Then unmask the entire
thing and enjoy. Now if you wanted to get fancy you could shoot the
entire exterior of the trailer with clear. That would make the finish
into a gloss coat, Then have the interior sprayed with bed liner.
