I've used them twice with great results but you're right in that they give off some fumes. I think there's less odor than a Tamiya spray can, perhaps to a significant extent. Because you use them in an airbrush and therefore control the amount of paint being sprayed rather than a rattle cans tendency to blast paint and propellant everywhere I found them less offensive. The paint itself is thin and requires multiple coats to acheive full coverage plus you then need a gloss clear coat to finish the job. If you want an auto color that's an exact match to the original then give them a try. I did and despite having no complaints I probably won't do it again. The last thing I need is an another brand of paint lying around in a partilly used bottle.
