there are 3 types of imron on the market today.
1. imron 5000 singlestage, 2-component 3/4 gallon w/1 qt.activator.
2. imron 6000 2-component basecoat, 2-component clear. also 3/4 fill on gallon of basecolor.
3. imron 333 2-component 3/4 fill single stage.
#1 and 2 are high end fleet finish' pete,kw, etc.price for lets says red in single stage 400-500 per gallon. good stuff but drawbacks are super slow "tackfree" time, in other words if shop doesn't have bake cycle on booth, whatever lands in paint say 1.5-2.5 hours after spraying will stick. then of course need to wetsanded and buffed out.the window to wetsand is long wait then once completly cured its like buffing iron.
#3 is a line dupont came out with for a more affordable fleet finish. we use gallons of the black for chassis' and parts.
limited colors.same slow dry make sure u use accelerator.wouldn't use for topcoat unless it was a beater.
i've been dupont shop for over 20yrs.we dont use imron for topcoats on any of our cars. our system is dupont chroma-premier basecoat/cleacoat.excellent color,holdout,matchablity, and the croma clears have excellant depth and clarity.tack free time is fast typical dupont small window on wetsand buff but it buffs sooo nice.
just my 2cents.
good luck
