just picked up a 2nd hand camper trailer. trailer is galvanised however where it has been pounded by rocks it has some slight surface rust.
i'm cleaning up the rust however i'm looking at using underbody paint ( stuff's like bodyfiller in consistency ) for the high wear areas on the draw bar, under the mud guards and pretty much all underneath the trailer.
I figure that this stuff works pretty good underneath cars so why not on under the trailer.
has anyone had any experience with trying this?
good/bad reports?
or even any better suggestions?

WURTH make a good stone chip resistant undercoat like that. It wont matter what you use underneath it will all disappear on dirt roads eventually.

I have a camper trailer and a tandem trailer, which I sprayed the underneath with Motospray Sound Deadener. I had the use of a fork lift, just lifted them up, covered shackles, springs etc and sprayed the whole underneath.
Did it when new about 6-8 years ago - a little thin where stones hit but still reasonably ok.

Used [forgotten the brand] an underbody paint that was thick and black like tar on our 1st campertrailer before going to the snow/flinders/birdsville track ect , sold that c/t 18mths ago , an underbody wash and "tar" looked as if freshly applied.

We used to use this great stuff in the Navy called "Tar Epoxy" for landing craft decks. It would stand up to the tracks on Tanks and APC's. It was a two pack product with a bitumen like fill. Great stuff, but would probably double the weight of the trailer.

Any mug can be uncomfortable out bush
