FT,
I have to tell you, if it wasn't my persistence in getting the business going, I would have long given up. Putting up and getting the booth approved was an absolute disaster. The booth I have is just an older crossflow booth...a mid '80's Binks booth. In fact, this is the exact style booth that I used when I first started painting. It is a 26'x14' auto booth...and believe me, I can fill it up with parts!!! Sure comes in handy.
It did not come with a UL number which was the main problem from the very beginning.
Anyway, once we bought the booth, we tried to do everything by the books...the electrical, the permits, the fire system....my advice to you is check your local codes *first* before doing anything. Our $4000 booth is now a $10,000 booth. We had the fire marshal stop by about a month ago....and low and behold he gave us the "thumbs up"
If I were to do this again, I would definitely have went with a new booth. We do have a Flames Board member that sells booth, I can't remember who it is (If this particular person reads this, feel free to post a link to your business or who you work for). Post it here *and* in our links section.
This gives you some insight of our booth. Again...my main advice is to consider a new booth, even though the costs are more up front, you may find that they may actually be less...plus you will have a "brand new booth"
