Hi, I've been doing epoxy and high build work in my home spray booth without any great issues, but now that I'm doing base/clear, I'm having trouble getting rid of the "fog" from the clear. I did the chassis yesterday, which takes a lot of spraying to get all sides of the chassis and crossmembers etc. The base exhausts ok. The fan I use is rated at 1990 CFM and pulls hard. I use three layers of pre-filters (about 1/2" thick, plus activated carbon filter to help remove fumes. The pre-filters get clogged with clear pretty quickly, so be the third coat of clear, they're pretty plugged up. It's still exhausting, but I get a pretty heavy fog in the booth. I'm using an Iwata 400 lpx HVLP gun. I could change the pre-filters between coats, but don't like to disturb things between coats. Is 2000 CFM way undersized? The booth is 10'x24'x10' ceiling. I'm an amateur obviously, but would like to improve conditions if I can. Thanks, Bill
