I can definitely agree here but for a lot of us those prices are a deal breaker especially when you have a family to take care of. My Charger is probably the worst paint job I've ever done, built a new booth, had water filters in the lines and it still gave me fits but I learned from it. What I learned is an all metal booth no matter how much you scrub is nowhere near as affective as plastic and humidity is an absolute killer. In the end I was able to fix most as I went and buff out the flaws so I'm very happy with it but still feel there's much room for improvement. The last car I painted before the Charger needed very little bodywork so start to finish was quick and sprayed in a plastic booth, didn't have to touch the paint afterwards at all, no runs, no orange peel... perfect other than one set of fly tracks on the dutchman panel.
Since then I've been building a new garage with emphasis on climate control and won't waste money on building another booth but instead go back to a plastic booth. My paint area will have radiant heat in the floor or radiators as to not move air while maintaining a comfy temp and there will be A/C to keep humidity at bay in the summer.
We'll see how it goes on Dad's truck which will have about $1,000 in materials.
