If you have a brand new never been in the water gal trailer would painting it prolong its life. Or any other coating.

No 1 is fish oil
On my last fishing boat I also ran a sprinkler type hose through the channels and flushed out every use.

I will second fish oil, squirted on with an inexpensive engine cleaning gun.

Coat it with Lanotec Steel-Seal. I use it on all skin fittings and motor. It keeps everything like new. You can clean it off with engine degreaser and your trailer will look like new again.

Does spraying with Fish Oil leave a sticky surface - i.e. when you touch it a week later, is it like wet oil, or a smear of Vaseline, on your skin?

No it dries

Painting over galvanising is not easy. The surface has to be specially prepared, and sometimes a light sand blast is used. Alternatively it is left to weather. If some of the paint comes off, the exposed gal becomes more vulnerable.
All in all I dont think it is worth the trouble painting if it is a good gal job.

Sure, if you have a hot dipped trailer I'd use Industrial Cold Galv paint or if you don't mind a black trailer bitumenous paint like the SCA underbody will seal the zinc and the trailer will outlast the boat. www.supercheapauto.com.au/p/sca-sca-underbody-rust-barrier---400g/395325.html
I used it to paint my rear section of the galvanised RHS trailer and kept the rust away for last 6-7 years. For top section I wanted it blue so I used 50% Killrust + 50% Penetrol for initial coat, also no issues after 6-7 years and trailer completely submerged in swamp brine at the local boat ramp.

+1 for fresh water, but down the track and for those that haven't discovered it, get a tin of Tectyl 506. Looks like crap but works great.

+1 for Tectyl 506. I painted my anchor and chain with it.

Cisco, how does the Tectyl cope with regular immersion in salt water and abrasion with the seabed, I was thinking of doing something similar.
