Beware of wrong, and in this case downright dangerous advice. A filter mask DOES NOT protect against isocyanates, you MUST use an air fed mask, and obviously the compressor MUST be sucking in its air supply from well outside the paint booth.

Yh thats a good point a bout the ccompressor

If you want even cleaner air and have lots of money you can buy the filter regualtor from sata

You will need a filter regulator, or a suitable design of compressor (diaphragm instead of piston), to keep compressor oil out of the paint and your lungs, so you should use one, but I seriously doubt that it will make the slightest difference to small molecule toxic substances such as isocyanates, so don't rely on it for that.

 

The point I have been making is that you need to carefully consider ALL routes that isocyanates can take to reach your lungs or skin, and prevent them all, so basically everyone needs to examine their own setup carefully.

I do agree about the last point but disagree with the first point as you can rely on a sata filter regulator from a piston or diaphram compressor and makes a huge difference in what you breath even small Unwanted substances
But all that cleaning comes at a price

I have my compressor in a different building to where I paint, I run the air in solid pipe with drop legs and a normal filter regulator at the end, when I am painting I add a coalescing filter after this and use food grade hose to my belt regulator that has a carbon filter built in, biggest problem with home 2k painting is getting enough air for the mask and gun, many link two compressors. I chose to use a low cfm gun when using 2k so one 14cfm is ok, just. My gun is a devilbiss sri pro which when set correct gives little overspray, then I have filtered extraction from the garage. Dust can be a problem as 2k dries slower than cellulose. I have found the smaller gun gives a fan plenty big enough for painting a mini.

As ive been looking in to painting the car as well, if you have all the equipment already get some old panels from a scrappy, bonnets or something and do some practice on old panels first (stripping/filling/prepping/painting) get some confidence first then transfer it the car and hopefully by the time your there the bit of practice may eliminate any major mistakes. Bit of experience can go a long way, You dont want to be rubbing the whole car back down and starting again if you mess it up

See... No one quotes me in this thread so I just figured it was dead.

Glad to see it's alive and well haha!

Also, I think isocyanates in paint are illegal in Canada now.
