Hey Goldie, good to see u cranking along....
Rusto and Magic are similar air cured enamels chemically....adding the hardener brings either closer to a 2 part solvent cured paint system. Straight enamel will remain semi soft after cure, but hardened it dries quicker with a harder shell..and dry quicker when spraying giving less runs ..it will be more durable, a bit glossier, and easier to keep polished clean...that's about it.
BTW those guns youre looking at aren't really the best bang....the HF pro gun is an air hog..requiring a ton of air to catalyze......and the starting line DV isn't any better than ur typical china knockoff. If u want the gun just for a few projects, then the purple HF guns will do fine if u clean them before using...and they only use like 6cfm...the HF pro sucks 15cfm/40psi.....if u want a gun to use regularly, its better to get an upper range gun like the devilbliss gti, or a binks m1g or Iwata....
bottom line is, the low end brand name guns are no better then the 20 dollar gunsm just 3-5 time more money. JMO
