I'm going to paint the underside of the deck (brown wood ply). What about the top though. I don't suppose it would last long after a load of premix? I've already given it a coat of protectorol. How about a polyurethane?

i would apply a couple of very well thinned coats first, so they soak in deep.
i would not bother. you should get 5-10 years out of the ply, depending on use. they usually break rather than rot unless its keep wet. then just replace the ply, its not expensive. you will spend more in paint etc than what new ply costs.
the other thing is "brown wood ply". if its dark brown its possible you have the pre-finished ply. theres no need to paint it, its already been done.
I'm just going to use old polyurethane that has been sitting around.

Waste oil is the best,i paint everything in waste oil cause my brother owns a garage. Ply,fences even the deck on our house. You don't have to be miserly cause it's free,plus after 1-2 its dry,meaning no residue at all to come off on your hands if you touch the painted surface. Smells nice too for a few weeks,sorta like new car smell appeals to people

It's not a good idea to use waste oil for that purpose since it contains dioxins which are carcinogenic and thus a danger to human health. You would be prosecuted if you were caught doing that in Europe and probably also in the USA!

Best no one lick a trailer deck then, just in case.

Not dioxins, at least if the waste oil is out of a normal vehicle. But it will have have arsenic and quite a few heavy metals.
Probably best not to bath in it, but casual contact won't hurt.

Thanks "tony9" for pointing out that dioxins are not present in waste engine oil. I now realise that my posting was incorrect. A check on the internet reveals that the main contaminants are the ones that you have mentioned as well as polycyclic aromatic hydrocarbons.
