I have a steel trailer what paint should I use? I am looking for something that looks descent brushed on as I will be doing it my self. Ive heard of tractor paint such as this http://www.doitbest.com/Gloss+enamel...sku-774853.dib.

Any good expoxy paints out there

What about something like POR-15. It's a brush on self leveling paint. Some guys use it on their out drives. My brother in law uses it on his hot rod projects. I see your in NY. Depending on where, I had my steel trailer sand-blasted and painted with Imron for $600.00.

Alkyds have no UV and will end up chalking.
There are many good epoxies, ICI, Devoe, International.
These are industrial epoxies that can be reduced and brushed on with good results if you cannot spray them.
It is a good idea to give it a minimum of two coats of epoxy.
I would top coat it with a 2 part urethane, same manufacturer for both the epoxy and top coat for maximum performance.
If you want the urethane in a specific colour and the paint store says they can tint your colour to match, do not let them tint it out of a clear base, it will not cover and you will 5 times the coats to cover as opposed to a factory pack colour
Good luck.

PPG makes an industrial epoxy that flows easily and is very durable...we've used it on all kinds of metals with good success....it is actually a biotch to sand once cured...i guess it all depends on your prep work....

thanks for all of the help. I will be looking into all of these. I also called sherwin williams and they have an industrial enamel that they said might work good too

Stay away from S.W. enamel, its old technology and wont hold up. You can spray POR-15 if you thin it down enough with a virgin laquer thinner.Its very durable and stops the rust. I would recommend thinning it down alittle anyway so you dont see your brush strokes. Imron is good but not made for brushing and is also 25 year old tech. I would also recommend rolling as much as you can it may flow out better in the end.

I painted a galvanized trailer with nason epoxy and nason single stage.......A standard steel trailer is much easier to paint, i have done a few of them....I would recommend an epoxy before you paint. People recognize the name PPG and thier DP epoxy and it is good stuff.....But there are cheaper epoxys out there that are just as good....Oooops i didnt notice you wanted to brush it on, i thought you were spraying it on....

rustoleum !!!! best you can buy for the money period !!! flows out, nice shine use it everywhere !

My trailer was galvanized, painted it white with rustolium white very easy touch up. Not very high dollarjob but it was better than looking at a gray trailer.

PPG's Industrial Epoxy....tough as snails..
