My paint gun choice cost me a full respray on a classic Mustang
Last spring I had a 1965 Mustang come into my shop for a full repaint in grabber blue. I was deciding between my old trusty Satajet 5000 and a newer Iwata LPH400 that I had just picked up from a trade show. I went with the Iwata because it promised better atomization and less overspray, but I did not take the time to dial in the pressure and fluid settings properly. First coat went on nice, but by the third coat I had orange peel and a few runs that ruined the finish. I had to sand it all down and start over, which cost me about 12 hours of labor and $150 in extra paint materials. Turns out the Iwata needed a much thinner mix than I was used to with the Sata. Has anyone else had a similar issue switching between gun brands and found a trick to get the settings right faster?

Read a piece in one of the auto body trade magazines a while back about gun manufacturers using different viscosity standards for their recommended mixes. The writer suggested keeping a spray-out card for every new gun you use, with the exact pressure and fluid settings written on it. Sounds like that could save a person a lot of trouble next time they switch brands.
