So I purchased a portable inflatable paint booth on Amazon.
Exterior dimensions are 39'X20'. I could have saved a few bucks and purchased a smaller one but I like to have lots of room to move around in. Inflated very quickly. On one end is the garage door, I could probably get my son's sprinter in it. On the other is a prep room, its small but workable.
As you can see in the pictures its BIG.
Paint booth;
Inside pre-paint;
Inside primed;
Inside post paint;
So my conclusion is for anyone thinking about painting a car themselves it's worth it.
Thanks
