66 dart convertible

Since I live out in the sticks it's hard to find a paint booth to spray in so I'm working on a positive pressure pvc knockdown booth(in miniature right now)
it should be able to fold down into 2 sections that I can slide against the wall or put outside. here's some pic's of the basic layout. I'm thinking I can use the back portion to put T's in the one side to fit in some filters for the whole back wall on one side. each section will be 20 ft long 8 ft high and the doors will be about 7.5 wide giving a total of 15x20 booth(gotta measure the challenger to see if it's fit.)
