Need Some Advice

[Autocar]

My floor on my equipment trailer was about shot so I had a 21 foot log sawed into 1 3/4 x 8 inch planks I scraped and wire brushed the whole trailer now my question is what can I paint or stop rust that can be put on in cold weather. Trailer cleaned up pretty good so I would like to repaint it but weather wise not sure what can be used. Thanks Bill

Sherwin Williams  durplate 235. I use it to paint truck frames. It is tuff stuff.  A gallon the hardener and thinner. They may tell you its $200 a gal. The last I got was $70. Its very thick and will need to be thinned some. I use a $25 undercoat gun to shoot it. If you thin it right it works pretty good and is faster than a paint gun and it will shoot it 3 ft for the places a paint gun won't go

Looked into the Sherwin Williams 235 I felt that I just didn't have enough experience spraying a paint that has a hardner added to it. Talking with some local guys they told me it set up pretty quick. So I decided to take to to a paint shop the was familar with spraying the stuff. Guess that's why you lay some money back for a rainy day.

 Corroseal is a decent product, I found an off brand copy of it and had good results.

Waste vegetable oil can go on at any temp.  You can put it in a squirt bottle in the microwave if you want to hand spray it.  Itll seap into all the pores and chips unlike paint.. And then polymerize [react] with the iron to form a blackish skin that stops further corrosion.  It does not last forever but we all know paint doesnt either.  And its free.  Boiled linseed oil used to be the standard government approved corrosion inhibitor for the interior of airframes before the skins were rivetted on permanently.   Same thing.  Linseed is a vegetable oil, it just reacts faster than others which is why its a fast dry additive for oil based paints.  Heating any oil makes it thinner (less viscous) so it creeps deeper and reacts more, thats all.

It also works pretty well for wood and doesnt care if theres dirt around.  Its oil.  Its happy to coat and soak into anything, yet never form a hard chip to later flake off.

Just a thought, I also use waste vegetable oil for the planks on my trailers. We eat it, so no one can really complain too much if it drips once in a while, and if the planks are at all dry, it soaks in like linseed, but as mike mentioned, its free (usually)
