from a part time detailer...
lots of information on this thread, some good, some not.
the term wax now a days gets used everywhere, when in fact most products are either sealants or hybrids. Wax is usually carnuba, and doesn't last that long, and will attract pollen. A sealant is the way to go unless you want to redo the work every 2 months. Rejex is a good sealant, but there are tons of good products out there. (Collinite, Duragloss to name a few)
be careful of anybody that sells high speed buffing, it's more a marketing term than anything!
for a fairly new trailer you just need a good sealant, if you have some oxidation, a sealant/wax with cleaners will do the job
-if it's bad oxidation, then you want a polish/compound, but that ain't cheap
I you want to find a competent person to do the work, go on a forum like autogeekonline.net and ask for referrals that are local to you, and you can ask all the questions you want! The online detailer community is very good at sharing knowledge and giving feedback on what you really need!
and a guy that charges 5$ an hour is not a detailer, he's a hack and can cause more damage than you can think!
