[Grumpy old man]

I'm a firm believer in "do it yourself" but your not going to be able to get by with any 110 volt / 25 gallon compressor doing body work let alone spraying paint . you'll kill it in the process

Here's a suggestion . Run it by your local Maaco auto paint and talk with them , You could pull the trim and glass and buy new gaskets and glass for what you'll spend in materials and time doing it yourself if your not looking for show quality paint job you would have it done way faster and considering all the costs involved you could be way ahead $ and time wise . Any decent body shop willing to spray over your bodywork won't be guaranteeing anything . Just finding a shop to spray it after your done doing all your own work is tough , They make more money changing pre painted bumper covers
