Yuk. But I suppose it is ok to use if you don't get on with your neighbours!!!
So what is the problem with polyurethane, is it similar?

Spyder : True it contains cyanide, but then so did sweets many years ago, and writeable CDs have it in them, and old wallpaper. To paraphrase from
this month's Car Mechanic's magazine, Sodium Chloride tastes great on chips, but Sodium Chlorate is one of the most powerful weed killers
and does anything but taste great on chips. Just because it contains similar elements doesn't mean that it has similar properties.
Incidentally I'm not trying to play down the dangers of 2k, it's still not something to disrespect, just trying to get burst the myth that
2k paint "is like cyanide". You won't drop dead from a whiff of 2k, hell, you could probably do a whole car with a charcoal filter
and not drop dead, but it would have severely and permanently affected you respiratory system, and who knows how much or little it would take to
completely finish you off.

It's the isocyanate component in the hardener that is carcinogenic according to the paint shop across the road. Cyanide is also a cumulative
poison building up over the years till it reaches a level where it will affect the user.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Agreed,
But everyones tolerances are different!
What might take several months of exposure to one person could seriously affect another after a few minutes exposure.
Is it worth taking the risk just to prove someone wrong?
I worked in an envirnment where you had to use the correct equipment or you didn't work. Health and Safety was taken very seriously. Yet there
were still a couple of people who were affected by the stuff and they used it a lot less than others. They now have serious health problems.
Your simily with salt, bears no comparison. Chloride and chlorate may be different, but cyanide and cyanate are not.
Lead used to be used in a lot of things because of it's properties and is a poison. It has been banned because of the health hazard is poses,
yet cyanide is more toxic. That is why it has to be used in a controlled environment with the proper precautions.
If spraying at home stick with synthetic or cellulose.

I'm not a Doctor (trust me!), but we were always told that isocyanate is cumulative. The stuff stays in your body and when your individual
tollerance is reached - you die.
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

are polyester, polyurethane, or acrylic.
I think the universal hardener will be for various different makes of paint, as opposed to different types of paint resin.
Different resins need different hardeners/catalysts to set them off.

I sprayed my nosecone with polyurethane paint, to ensure it didn't stick when I took a mold from it and believe me it is well strong. It fell
off the table bounced off a set of metal racking, off the car, off a set of wooden ramps and hit the floor (dented part of the car) and there was no
damage to the paint other than a small indentation the size of the end of your finger nail!
And rubbing it down was a real bitch.
By the way I won't use Pollyurethane paint again after reading this thread!

What is the best way to tackle 1K paint and how much does it cost?

Discussed it a little earlier on in this thread, but if you want metallics - used standard polyester basecoat (no gloss - easy to spray) and then 1K
lacquer (use straight from the tin - no thinning)
Cheap polyester costs about £18 per litre and 1K clear is about £45 a gallon (i know smaller quantities are available but dont know the cost).
You could also use cob (clear over base) for non metallics is you want. Nice deep gloss and a little more UV stable on reds. The 1K clear will degrade
after a few years out in the elements - but should be OK for a car that is garaged most of its life.

resurrecting this thread...
I've heard rumours that celly, 2k etc are no longer available. Is this the case?
What are these new "water based" paints that are supposed to replace them?
