Question about hardener... HELP!

So I have already painted my car... and it looks good... used the following mix 8:4:1... 8 being paint, 4 being the reducer, and 1 being the hardener... at this point I have run out of hardener and want to paint a couple of invidual parts... how important is hardener... this is 1 stage paint.... with the hardener the paint dried in just 1 day although I'm sure it's still curing inside...

To the point question: Do I really need hardener or can I do without it? I'm aware that my paint may take a bit longer to dry, but will not using hardener affect the paint itself as far as color and texture goes?!

THANK YOU!

that's just what the instructions on the side of the can said.. it's one stage, so 8:4:1 is what was reccomended...

i just don't really know what to think about hardener since the old guys didn't even have it back then and their cars turned out good.... only reason why i'm questioning it is because i paid 20 bucks for a pint a few months back, today i call the same place and try to buy some more, same ammount, twice the price... seemed kinda flaeky to me...

you follow the instructions to the tech sheets TO THE LETTER. Every paint product out there is different. Some are 8:4:1, some 8:1:1, some are 4:2:1. It doesn't really matter, you do what the paper that came with your product tells you to do.

YOU NEED HARDNER. Folks back in the day used different paint. In early days paint use to harden when solvent evaporated from it leaving only solids. The paint you are using is chemically completely different. It hardens by a reaction of hardener with the paint. This reaction is what converts liquid into solid. Without hardner, you paint will never solidify (although eventually your solvent will evaporate and you will be left with kinda dry, gooyee, soft mess)
