[AT] respirators and Isocyanates (Urethane paint)

[Terry Welch]

No paint system is perfect. I did some work trying waterbase paint in field repairs for GM some time back. At that time all the lines had to be stainless steel because of corrison problems. I just painted a fuel tank on a Farmall M a couple of days ago and used paint fron Case-IH. They have refomulated the paint to be a faster drying and you do not get over spray all over like the old enamels use to do. I did us hardner and a approved mask. Not supplied air which would be nicer. But the mask did its job. I have to paint a hood on a Cat PL20 in a week or so and will use Nasson on it. I also have to paint a car for a barrel train. It will be Cat yellow.We will see what that enamel comes out like.

This whole issue is why I have started using water based acrylic paints on a 
lot of our industrial work (when I have the option to choose the paint). 
They are a bit different to work with but do nice work with NO VOC's 
(volitile organic compounds).  I don't know if these paints are available 
yet for automotive type applications.  I'm tempted to get some tinted to 
Persian Orange #1 and try it on some tractor parts.  I've used it on 
structural steel and it gives a very nice, slick, shiny finish and is very 
durable once it has a few days to cure but I'm not sure it's automotive 
quality in appearance.  The first time I used this stuff was over 15 years 
ago on the exterior surfaces of a steel construction package sewer plant.  I 
go by every now and then to take a look at it.  It's still slick and shiny.
