I am planning on keeping the original wheel arches to stay with the car, so it can be returned to original if a future owner chooses.
The benefit of having my own booth, is that I can work at my own pace, and paint every step. I would be back and forth to a booth a heap of times for epoxy, then high fill, then colour and clear, then possibly flow coat and then any other separate parts like the cage, bumpers flares, etc. So it would not be worth while. This booth was cheap and it works great.
I am starting to film a new series on how to paint a car, so I will hopefully cover all that stuff. The mask is from Sundstrom and it has 3 levels of filters in it. It is what professional spray painters use.
