i goit the full air fed mask from machine mart and ive got the biggest compressor you can run on single phase , the ratio is 4:1:1 i use 4:1:2 so i just put a little extra thinners in its easier to use than cellulose its the akzo nobel s2000 range from my local motor factors , i just hosed it on wet on wet its difficult to get it to run it holds up well.rich
Just put a vent hole in the wall near the compressor and box it all in so the air comes from outside, also makes it quieter.

refitted the bonnet tonight with the made up of 2 badges badge i prepared earlier , there has to be an easier way of refitting the rubbers , the paint is as out of the gun and will be left for a while before flatting and cutting but it looks pretty good , ooh yer big green shiny booger!

no you dont need to cure it although air drying season is fast approaching i would say do not paint below 12degrees otherwise yoiu risk blooming of the paint , the 2 pack dries in a few hours , it chemically hardens , this bonnet was painted on sunday over 2 coats of 2 pack epoxy primer the previous week, i used the air fed mask from machine mart with the belt and filter , it helps that i spent 15 years spray painting products in industry but im still learning about automotive refinishing, i use the machine mart gravity fed gun , it can be done at home but you need the equipment , the poisoning thing , i thought id done it this time as i forgot to put my flexible duct to the compressor outside so when i was spraying the compressor was taking air from near the painting area to my mask ,its easy to make a mistake as i did ,read up on the effects of 2 pack paints as they can cause lifelong asthma , the isocyanate is heavier than air so it will lie at ground level , so its recommended that a downdraught booth is used , it does surprise me that these paints are sold no questions asked to anyone that goes in the motor factors. if i can be of any help please ask , rich

2 pack generally gives a better finish than celly, and is actually easier to spray as it goes on thicker and doesn't run as easy.
The big advantage over celly is that it is a much tougher paint, last much longer than celly and holds the gloss much longer without needing so much polishing.
You've got to take the safety risks seriously, but also you've got to consider how much exposure your getting, if you use a air fed mask, and only do the odd bit of spraying then your risk level is going to be very very low, it's pro sprayers that handle the stuff day in day out that are really at risk. Also you want to prevent skin contact, pro sprayers wear those paint suits and laytex gloves to protect themselves as much as preventing dust etc landing in the paint.
Whilst researching my leukaemia I found that there is a strong link to Benzene, for most people Cigarettes and petrol fumes are the main point of exposure, but I've never smoked. Toluene is a similar chemical and is also strongly linked to leukaemia, this is the main constituent of thinners (including celly thinners), which I have had a reasonable level of exposure to, including often washing my hands in it to remove paint etc. However I don't handle it day in day out, just at "hobby" level. I'm not sure of any link in my case, but I'll be taking no chances in future, mask and gloves at all times for me !

Bruiser's two-pack coat is straight from the gun as you see it here:
No flatting or polishing was performed at all due to the finish I wanted. As it's satin it might behave slightly differently to gloss though I wouldn't have thought so. No runs or orange-peel at all & it's holding up to regular use extremely well despite the lack of a lacquer coat. A few light scratches here & there but on the whole it's coping admirably.

2 Pack will give you "gloss from the gun" if applied correctly.

I think it is commonly accepted that 2K is far superior to Celly. Celly primer sinks and "modern" celly has had so much taken out of it to meet EU laws, it gives all sorts of grief ... wont go off readily, wont mop up well ... in fact it has become a nightmare.
BUT, unless you have access to a booth, or have a workshop out of the way, you are stuck .... isocyanide is not nice at all ..... it enters exposed skin and has a cumulative effect on your body ... it stays in you, builds up and builds up, until you go one paint job too far!!
Also, I have witnessed 2K that is far from robust only yesterday ... a purported £5k paint job on a mk1 Golf ..... under the ramp, oil dripped out the diff of another car onto the roof (white) and eat in!!
I am of an opinion all paints have had so much taken out of them to meet pollution / poison reglations that they are far from robust any more .... celly was glorious years ago. Air dry, tough as old boots, flat it to your hearts desire, mop it like a madman to get a glass finish .. not any more!!

My Father worked as a spray painter for 25 years from 1965 to the early 1980's. He used all the correct safety gear that was available at the time (which was limited), and was ok for most of that time. Towards the end of his career, he worked for Ford, in their paint shop, spraying Transit vans that required bespoke pant colours for other companies, and was asked to trial the new 2 pack paints when they first came out. There were no air fed masks as such then, and the dangers of 2 pack paint weren't necessarily widely known about. He now has industrial asthma, and has had it since 1985, and he is the only one of his original team of 3 men still alive. 2 pack is evil stuff, and definitely requires a great deal of respect and care.rover100rich said:

i hear what you say and i was in painting for 15 years although single pack acrylic mostly for tv etc , talking to a chemist some years back he told me that the paints had developed over the years and to quote , there is not as much free isocyanate as in older 2k paints , i cover all of my skin and use a full mask and gloves, lots of people came into contact with things years ago , i have an uncle who is on oxygen from working in the steel works and another who is suffering the effects of asbestos in ships ,as you say take every precaution you can,you can imagine it does a great job inside your lungs , but you know we can tell people till your blue in the face about cigarettes and people still smoke , my dad died aged 49 of a heart attack , i havent smoked for 15 years or more now , may we learn by the mistakes of others,good luck ,rich

To be honest I am not in favour of 2 pack paint solutions, not because of health risks but simply I dont like how the finished job looks....to me a classic car should have a classic paint system applied and 2 pack in no way looks like the origional factory paint finish, to glossy to "plastic" looking.
On the other hand cellulose when properly applied looks wonderful and here is where the problem starts, getting the cellulose applied properly with all the correct rubbing down between coats and clear coats if needed is a long long process where as 2 pack is simple and quick to apply and gives good results when properly applied. I would suggest that any one who cannot decide on which to opt for should hunt out a properly done cellulose paint job by a master car painter....they are getting hard to find these days, but if you do find themthey will take your breath away.
