Hi Bryan,
SHORT ANSWER:
What the other guys said!
LONG ANSWER: ...... EDITORIAL: Please read at your own risk.
A few alternatives:
1. Use a friends safer set up, even if you have to drive some distance to get there.
2. Contact your local auto paint shops. I have had some of my RC planes fuselages painted in their paint shops by them. The price was reasonable, and NO harm was done to my body. Just as importantly, no harm was done to my marriage! ;-)
3. Paint outside if possible. I know it is not perfect, but it's your body!
4. SAFEST SOLUTION: My solution for the past 30+ years has been to use "Monokote". NO medical problems for your body, NO poisoning of the wife and children, NO weeks of drying time, NO stress cracks, NO headaches, NO 1,000 hours of polishing, etc. :-) .... This method will also be lighter than 95% of the painted CL planes out there.
5. COMPROMISE TO ABOVE: Limit the amount of poison paint by just painting the fuselage, and using film covering on the wings and tail, they have by far the most area.
I have lost 3 close friends to Cancer (ages 48, 57, 61). All were modelers who sanded and painted most of their planes, used epoxies, etc. All three had doctors that told them their model poisons were most likely the main cause to their cancer. NONE of them smoked, or had any family history of cancer. All three of them had wives who begged them to stop using these harmful chemicals years before they died from them.
It is your body, and your family members bodies that will suffer. Only you can say if a "paint" finish on your model plane is worth dying over. IMHO if you do not set up a completely safe environment for painting (like the professionals have to do to be safe) then I would NOT paint. It sounds like the set up you propose falls a little short of a safe environment?
But, this is just my opinion, I could be wrong, it has happened before. ;-)
Off the soap box
