When using any paints, primers or sealers that are 2 part or even single stage always read the label and follow the safety precautions.
You should also read the
MSDS sheets click the link.
These chemicals are very toxic and ARE hazardous to your health.
A fresh air system {for breathing} is best when spraying the products.
wear gloves, eye protection, and use caution when handling the liquids when mixing and a shoot suit gloves and some kind of appropriate respirator for the product when spraying.
you need a well ventilated spray booth or at least a shop with a good exhaust fan to evacuate the fumes.
you also need a controlled environment {heat} for the product to work correctly.
Follow the mixing ratio's and closely measure each component and again read the label for each product as they can be a different ratio. It is also a good idea to get the production or "P" sheet for each product if possible since most of the instructions on the labels are to small to read.
Most urethane paints and primers will stick to EVERYTHING so unless you want to clean over spray off everything in you shop or garage cover everything or build a spray booth even if it is a temporary one.
once you think your ready to give it a try buy the product from a near by paint supply shop.. IF they will sell you the product ask for their help. A lot of the new water base paints they will not sell to the general public. I am not sure if this is state laws or company policy?
the environment your spraying in, preparation habits, film build, dry and cure time and many other things make for success or failure. This is only the tip of the ice berg when doing body and paint work. it truly takes years to understand and be proficient when doing the job.
Start with small projects and go from there.
good luck
