hi guys - here in the good ole noth east[mass] we have a climate that feeds rust and accelerates it-my question is should i bother to paint my frame or oil it---painting would probably be a recouring thing--oiling would be easier----but are there any drawbacks to oiling?

Yeah its a mess having an oily frame. We have a 72 jimmy at work and they tarred the bottom of the floor. Its horrible to work on, you constantly get oily and sticky and it sucks.
If you use good paint, and properly prep it wont wear off.

I plan on oiling mine. Just a light spray and drive down a dirt road. My brother did it last year and noticed a big difference between where he oiled and where he didnt. It will be messier no doubt, but shouldnt be that bad.\

Before I sold my 84 I sprayed the whole underside with a motor oil/wd40 mix about 70-30%.
It was messy for a couple days, but once everything soaked in and the exess dripped off it wasnt to bad.

I've used drain oil on my trucks,it doesnt take long for it to wash off though,unless you use oil drained from diesel engines,the soot in it makes it cling longer and the bit of diesel in it lets it penetrate somewhat better...
Some off roaders I knew used Linseed Oil to coat the undersides of their Jeeps and the frame rails,once it dries it stays on pretty well,and dont need to be re-applied all that often they claimed--said it made mud a lot easier to wash off too..
I would say oiling a truck is easier and probably works better that just paint or undercoating does..it'll creep into areas paint would never see,and at least delay rust longer than paint or undercoating will...and drain oil is FREE too,where as the other 2 choices would cost you...I have seen 60's cars that were serviced at a local gas station since new,and the guy always sprayed the drained oil onto the cars to "get rid of it" ,they still look like new underneath,and most were driven year round too..
One elderly lady's '67 Impala was so clean underneath I'd have sworn it was a southern or arizona car all its life,but it never left Cape Cod!..

Dirt will,but once enough dust coats the oil,most everything else just runs off,like water,etc..it would be best to wash the underside off each spring and re-apply the oil fresh,in case some salt does stick to the dusty oil...anything is better than leaving it bare metal ,even if you wash it religiously..
The most rust free GM truck I had was my '79 Bonanza ,its 250 six leaked everywhere--the valve cover,side covers,front timing cover seal,and the rear main dripped some too--all the iol got blown back by the fan to the firewall and under the cab on the floors,and though it was a mucky mess to work on,it was in remarkable good condition underneath!...I made the mistake of fixing all the leaks and pressure washing it clean,and within a year,it had looked like I bathed it in the atlantic ocean...
..should have left it grimy and let it leak..

So what's the best way to spray it on?
Id sprays a good bedliner on it real thick. DONE.

I've seen too many cases of bedliner getting bubbles under it and the metal rotting away from it. Oil works really good, and you don't have to worry about wires, cables, nuts, etc from getting "painted on" by bedliner.
Thin your oil down with diesel and spray it through a garden sprayer, or an old paint gun that you never want to paint with again would work too.
Somebody tar-ed the underside and inside the panels on my 69, what a mess when I started welding in patch panels!
(Not to mention, it rusted out anyway!)

Well if you bedlined it you would wanna kill all the rust via sandblasting or wire wheel, then as long as you follow directions there should be no problems. Heck if ur that worried, bedline it all, then oil on top of that
