Kind of like Scott's deal, several guys around here have prepped the car theirselves, scuffed it with some 3M pads , bought their own paint, then took it to a Macco, or another el-cheapie place called Peach (Peach may be a chain???). They know how to spray OK, but from what I'm told, they will spray a car just like it rolls in, and if you want them to fix somehting, you have to point it out and pay extra for each dent/ding repair, etc. Another problem is that if you have paint peeling, they will paint right over that too, so you'll have to sand those areas and smooth them out with primer or soemthing...
The probelm is preping it, then getting it there without getting more debris on it... It would be nice to know someone with a enclosed trailer that could transport it. The last step is to clean every surface with a really good degreaser... I do know that you can't touch the surface to be painted with your hands, or it will create fisheys in the paint...
One of my College instructors told me that he painted a truck by making a paint booth in the garage... He made a frame with PVC pipe, and used some good thick plastic wrap type stuff to make the booth. Then he incorporated some A/C filters in each end and fans to move some filtered air through...
My redneck neighboor had a friend paint his 72 F100 in his driveway just after some rain when their was less dust in the air... It looks OK, but there is definately some noticeable grit, and even a bug or two in places. In his case not very noticable cuz its kinda metalic teal...
I have access to a military auto hobby shop with a paint booth, just have to get your own paint gun, filters, and water separators. I may try it out on my old truck, and if satisfied, try the 35th....
Just some ideas... I was gonna paint the 35th a couple of years ago, and never did... Ended up using some walmart touch up spray paint to stop some severe flaking.
Good luck!
