For those of you looking to purchase a new booth, you may be interested in our most recent blog post on paint booth compliance. It talks about the general process/requirements in making sure your paint booth meets code.
Since code compliance is a very local thing, regulations vary from state to state, city to city and county to county. If you have particular information about what is required for your area, feel free to share that as well!
