Any suggestions as to wood preservative, primer, paint, &tc. to use

Thanks a heap,

If what you did pealed it probably wasnt done right. If its really all
bare wood, you are lucky, I would stain it, and not paint it, with
first oil stain to seal the wood. The most important thing you likely
did wrong was paint a warm- hot surface, or in sun. You dont want to
paint a warn-hot surface heated from sun or one that will be soon in
sun. I know its hard to plan but after the sun passes or a cloudy day
is best. Even after sun passes surfaces cant be hot if you expect
paint to last. Go to a real paint store that sells only paint and use
what they recomend. Most paint issues are errors of the painter. If
you must have paint old fashioned oil primer and latex top coat is
best. Not quick dry primers. Stain done right will not peel, it will
just wear away but need recoating sooner than paint. If it was me id
spray it with oil stain, and in a few weeks or next year spray it
again with latex stain, oil as a first coat will stop any bleed
through that might happen and get deeper into the wood.
