The taping part isnt a problem being a house painter I do use tape a lot , (I bought some nice 3m tape to work with) when I use oil based paints I know to take time to peel it.
I just bought a new hvlp gun and new compressor so I will definitely practice and make note on pressure , my old compressor can't handle the hvlp the new one should be good, As soon as the rain stops around here I'm going to try it if I do a crappy job a friend that paints cars will help me next weekend, unfortunately he isnt much help explaining lol.
I decided on using a gray primer and most likely a 1969 Hemi Orange, going to paint the junk fender and put it on the MJ to see how it looks. Once I do I will post pics, I'm using a 1 stage Dupont paint, since I'm not experienced with auto paint I don't want to mess with laying on a clear coat, probally going to let a pro clear the mj after I finish.
