A word of moderation here, Imron, besides it's toxicity, is yesterdays technology, there is no good reason to use it to begin with. DuPont 50P Polyacryl Anhydride Enamel emulates the qualities of Emron without the isocyanates. However, I have sprayed Emron using a good commercial quality dual charcoal filterd mask, in a well ventilated area. Several times, I live and breathe. Commercial Spray booths use a laminar flow to get the fumes out quickly. and if nothing else, when you spray any paint at home you need to get the fumes and overspray away from you. Spraying for a living every day or exposing your self to large amounts of poisonous substances for extended periods is the danger. The modern two part acrylic enamels, Dupont Centari, for example, used for auto painting are much safer than emron and produce an equally fine finish ( as far as models are concerned). You can add flex additives, gloss additives, hardeners and the versitility is far superior to emron. This doesn't mean you don't need to use a good respirator and air ventilation. If you don't have proper equipment, don't spray the auto paints, If you have the equipment and know how, (big if) by using reasonable precautions you can safely paint your airplane. If you live in a housing devlopement, with no opportunity to exhaust fumes from your basement witout polluting your neighbors, and you can't spray in your driveway, take your prepped part to a body shop. Usually if you look around you will find a quality craftsman who will take an interest in your project, do a good job and not over charge you. The new auto paints require expensive, appropriate equipment and a good knowledge of both technical skills and application. I use a $400 HVLP gun driven by an 80 gallon 5 HP two stage air compressor with Devilbis water filtration system. Total start up cost about $2000.00. How many models do you want to paint? As an aside, Heinz Weisenbhueller who refinishes full scale sailplanes with his M&H Soaring business, uses a high end auto aclylic enamel, PPG Delstar, not gel coat as many suppose. It flexes better, and does not yellow over time. There are a lot of other ways to get a great finish also, as in using a base coat clear coat, but that is another treatise. Regards, john Derstine

Only a fresh air source with a complete 100% suit. Charcoal/vapor respirators are not worth anything when dealing with this type of stuff. A lot of paint is NOT to be messed with! Any type of sprayed paint you should use a full face respirator at the minium, even with water based acrylics. Isocyanide type paints such as Imron, PPG enamels, Awlgrip, etc...all should be avoided at 100% cost! There is NO REASON to be using this stuff for RC use. Not for power, not for soaring, etc. In general we do not have the safety equipment to even handle the raw materials. All the time we hear of full size airplane and car restorers dying within hours of using the stuff. It is nothing to be messed with at all. Now, if you want to see some rather mild paints, try some of the single part linear polyurethanes for the boating industry. Still nasty stuff, but in general much milder than the isocyanides.
