Read Champ203dcx's post/ replies below, doing same thing, didn't want to hijack and maybe we can both learn something new

Have a co-werker with an automotive bodyshop/spray set-up, etc. Gonna spray my C-channel trailer w/ gloss black(over old faded black) for cost of paint only. I'm doing the prep myself, no loose/flaking paint, surface rust in a few places. He recommends NOT sandblasting to bare metal as current paint is decent but faded(tried compounding, just not enuf pigment left).

What grits, start to final prep, should i use? Do you wetsand in between coats or does this depend on the paint?

What paint(brand/type) do you recommend? Willing to use metallic if good idea(or not??). Gloss/semi-gloss/flat enamels---pros/cons? I'd like gloss if a good idea.

How much paint to buy for a Stratos Trail single axle for 19 1/2' boat and how many coats(over existing paint)? Highway travel over good roads, freshwater only.

Pinstripes? Buddy recommends leaving on pinstripes and painting over them IF I want to put on new pinstripes so I can just follow over top, says putting 'em on straight is a PITA. I may not want pins anymore, any comments/tips/alternatives/bling factors?

How long should paint dry/cure b/f getting it wet briefly to reload boat? He called a few paint mfg's, answers ranged from 8-60 hrs. Any experiences?

He's good on cars, hasn't done a trailer, open to any tips from BBC'ers as trailers may provide a new source of local bidness for him.

I don't need it showroom, but want it close! Any advice/suggestions welcome Thanks, B-O-B
