I use a kitchen hood in my (acrylic only) spray booth, and it works okay, but not great. Most inexpensive kitchen hoods don't have the CFM required to remove paint fumes and overspray, and often have unshielded motors which could be a fire hazard. And not just any fire hazard, but an explosive one! Mind you, I've never had any problem in the 3 yrs I've been using it.
So, even though I use one myself, I no longer recommend them for use as spraybooths. Besides, they vent wrong for spray booths. Downdraft or backdraft is superior for painting. You can buy kitchen hoods that do that, but they're more expensive than the Pace Gerald mentions.
If it's all you have to use, use it and use it proudly, but if you are going to invest money, consider saving up a bit more and get the Pace.
