I'm certainly no expert but from respraying a Mini I used to have, my biggest recommendation is to clean the gun very well after each session. I had good results at first but they got worse until I realised it was possible to take the whole nozzle assembly apart and clean with thinners each time.

Obviously can't speak for your specific kit but the spray guns I've seen that come bundled with compressors have been of quite poor quality. If you find it's the same, good quality guns don't seem to be too expensive.

I've no experience with gravity fed guns but the suction feed gun I bought used a lot of air, so if your compressor isn't large you may have to stop once in a while, although probably not an issue if you're just painting fairings.

Otherwise, just the normal stuff really, wet the ground if there's a chance of dust, rub down between coats with wet and dry etc. It's a great feeling putting on colour with a spray gun, so much better than an aerosol.
