Quite a novice myself, this is only the second hull i've sprayed. I didn't flowcoat though, i've painted it with Acrythane as a few other forum member have done, just using advice i could find on here and any other forum really. Really pleased with the finish, minus the bugs.... but theres not that much you can do about that when you're painting outside and it's bright orange.
I used polykote 4k primer and Acrythane top coat, it's a 2k paint so you'd be sensible to use a respirator etc.
Flatted the hull with 120 grit, (i had some deep gouges and a hell of alot of antifoul to remove). Repaired the damage with gel coat filler. Loads more sanding and i finished on 240 before primer.
Flatted the primer down with 600 then top coated.
I'm by no means an expert so i've literally followed what i've found on the forum and so far so good, just need to buff it up. Being paint i've found you've really got to get a decent surface before spraying, gel may be more forgiving in that matter, but comes with its own cons.
Setup, i've only got a puny 25l compressor but the CFM isnt too bad so i can run ok but the compressor is always on, definitely would go bigger if you can.
Spray gun was this one -
Scratch Doctor LVLP Gravity Feed Spray Gun - Waterbased , Solvent Paint & Primer | eBay again no complaints, used a series of water traps and pressure regulators, and i put a length of hose in a bucket of iced water before the first water trap (chepo air cooler :-)) worked well enough anyhow.
