okay thanks for the advice.... I think I will get a bigger shelter, also after talking with the painter again today, he said that if I was worried about the fan blowing across the car as mentioned I could maybe do with out it if I got a shelter with 2-3 vents in it and covered them with some paint booth filters then use his exhaust fan that pushes 2200 cfm's (also he said it has a 20 foot hose that connects to it) he said that would probably work well... he said it would create a sort of negative pressure... I also decided that I am going to buy a fresh air system then when done with it I could just sell it.... any thoughts on this?? would it work with the exhaust fan only... pulling air through the vents/filters??

thanks
