need help real bad

sup guys i just bought a front bumper for my 95 Ls integra and want to paint it right now.

for those with experience with spray gun painting...i need help

for primer:

should i get this evercoat primer
or
this nasson primer or should i just use dupli color self-etching primer can since it's the best primer from dupli color

and for clear coat:

should i get this rayflex clear coat
or
this auto paint pro clear coat
or
this nasson clear coat with hardener

is it nessary to put hardener and/or thinner?


thx guys
