no gloss, matte is much easier to touch up per what Mike said and what ive also experienced in the past.
matte is easy to paint too. just keep a constant 8-10inch distance avoid any close range sprays and it will turn out a nice matte finish. i also recommend going this on a warm day 70F+ and use 3 cans in rotation. reason being, rattle cans tend to loose pressure while you spray. as soon as the can starts to feel cold, change cans because the pressure is getting lower... otherwise you end up with a spitting/dripping mess.
dont ask how i know...
