Trailer Paint

Post by Raflad » Sun Apr 14, 2019 9:31 pm

Hopefully pretty soon I'll be ready to paint my trailer. Having never done this before I have a couple of questions. The trailer is in a pretty dry climate and will be under cover when not being used.

1. How much primer and how much olive drab do I need to buy.
2. How many coats of primer and how many coats of olive drab.
3. What is the best primer to use.
4. Who sells the best olive drab.

Thanks in advance

I use RAPCO paint out of Texas. Buy 1 gallon of red primer and 1 gallon of whatever shade green you would like (rapco has several with the descriptions of what color was used when).

I would do 2 coats of primer. I don't wait in between coats. Clean your spray gun, mix up the paint and then shoot 3 coats of the green. You can do more coats if you want.

You can get it completely done in a day. You will have alot of primer and some paint left over. I buy it in gallons because it is alot less expensive then the spray cans. I use Zyline for the thiner.

Thank you for the information. I checked out their website and will order a gallon of each.

Years ago Bill H. and I worked on my trailer. It would be cool in the mornings and hot during the day. Therefore painting was done when it warmed up but before the trailer was very long in direct sunlight, but before the temps got past the high 60s or low 70s. The first coat of Red Oxide was not cut very much, maybe 10% if I recall, there was an orange peel surface in the tub that this helped with. It was flipped over and primed the next mid-morning and a second coat with more Zylene was sprayed on everything else. The next day the tub was flipped over again and shot with the first coat of OD which I think was cut about 20% (?) and everything else got a first coat. That afternoon I think we flipped the tub and gave it a second coat of OD.

So, to recap:
Never shoot when in direct sunlight if you can help it, but don't let the metal start to get too HOT when you start to spray the paint onto it.
Check with some similar parts using the amount of Zylene to see if you have the correct size nozzle in the sprayer and are holding the nozzle the proper distance from the target.
Spraying new paint on paint/primer that may have a thin, dry skin is something I don't approve of, drying takes time even between coats.
Don't try to assemble things until they have set in the sun and DRIED. It was probably in the 80F or hotter later in the day after we painted each day, yet after the 2nd coat of OD setting overnight we assembled it and I brought it home.

Use the "fingernail test"....if you can leave a half-moon indent from your fingernail in the paint, it hasn't dried enough to be messed with.

I believe that even in warm weather, two coats of Red Oxide and two coats of OD will give you good coverage but it takes TIME (or a paint booth) to get that paint to cure. I figure that during summer it too a month or more before I REALLY felt the paint was hardening. I would never suggest you start sliding any kind of cargo around in the tub for at least that long or you will damage the paint on the high spots.

PS...when the tub was up on jackstands, painting inside of it elicited at least a half dozen drips where the floor was attached to the side panels. After the 2nd coat of primer, there were less drips and by the 2nd coat of OD, the leaks had stopped. A generous, but not sloppy application in the tub guaranteed good coverage and the "orange peel" was no longer visible. The dents in the floor were not excessive and gave the trailer "character" as they say.

Yes, thats it.

Rapco says 4 parts paint, 1 part thinner.

When I spray I usually just visually estimate the ratio using a clear large mason jar.

This paint is really forgiving and easy to work with. Just make sure you are wearing a paint mask.
