painting suggestions

I want to paint up the old WC, would like to give her a good shine and make it last. My question is, what paints can I use without going to the expense of a fresh air resperator? I just have a charcoal type and I typically paint outside or in my shop with the large doors open. I know I cant use the hardners safely, what kind of painting system can I use to get a nice paint job?

I use Vansickle paint from farm store and put hardner in the finale coat.  I paint outside and get excellent results. The paint has held up for years.

the hardener is the toxic part,so if you use that you might as well use any 2-pack paint.There is now a few companys selling 2-pack paints called isocyanate free,so you can paint with just a charcoal mask or less.

I suppose a mask of some sort would be the way to go when painting with any type of paint. When I get ready to start to shoot something with paint even with hardener I never seem to have a mask handy. Takes a bunch of scrubbing to get the tint off my glasses but does make it easier to get hold of the unwanted nose hairs with the tweezers.
I think it is a big problem with/for those that have an allergy to the fumes. I don't seem to have an allergy to any paint fumes. From what I have read it is not a chance a person should take if they have the information. When I started spray painting some 50 years ago most painters painted without a mask. I have been using hardener for over 20 years several times a year in small amounts but do try to keep air movement to blow fumes away from myself.
At 72 I probly will keep painting the same way when painting a project without a mask using hardener just as I always have. If I was to paint for long periods such as shooting more than one  tractor, truck or car I would most likely buy the fresh air system.

I painted my WD45 and 7080 with valspar paint and hardner. Make sure your primer and paint are compatible. I had no trouble but i did have to thin quite a bit. I used a small compressor on my 45,(it was close and i got the "hair" a week before the show) it did not have enough air flow to make the gun work as well as it should have. It turned out really well though, I didnt paint it back "factory" (all sheet metal and a few other parts are orange but everything else is black) but Im happy with it. The 7080 i "customized" as well but used a 6hp 60gal compressor the paint sprayed on wonderful.  

I use a charcoal mask all the time ,if your not sure of it change your filters on it, they should be changed every 3 to 4 paint jobs.Give your self good ventilation and once you apply your coats, step out of the room for 10 to 15 mins and let it flow out and the air clear.Also if you have one try using the HVLP paint gun .I have been working on getting use to it for the past few yrs.Im getting so I use it more but still like my old binks model 7 but it does put alot mot paint in the air then the HVLP
