Just a quick question has anyone ever used an electric spray gun in the past on there car, I've just bought one and plan on using it for prepping both my cars as I don't have a compressor at home, I chose the hvlp version as I have hvlp guns at work that I use with the compressor, are these electric guns a complete waste of time as my plan is to prep it take it to work spray it then bring it home to wet flat and polish

Cheers
