I've seen a few plastidip cars and they typically don't look great after a couple of years. If you're going to go through all the trouble of doing body work, I'd just paint it yourself.
Also, a PD kit with their sprayer is not much more than you'll spend on paint.
IF you already have a nice, large compressor, there are plenty of decent budget spray guns out there.
I didn't want to invest in a large compressor that I'd rarely use and have to deal with taking up space so I bought a turbine sprayer.
Below is the link to the one I used. I will say that my paint job is not perfect, but a good majority of that is due to a couple big mistakes I made in technique and prep.
Mostly, I didn't have a good feel for how much clear coat needed to go down to fully wet-out, so I have quite a bit of orange peel in areas. Also, I didn't use automotive drop plastic for my DIY booth, so I had old overspray falling into wet paint.

I do suggest buying different tips/needles for it ($50). I think the one included is good for base coat, but too fine for primer and you'd probably get a better result going smaller for clear.
For materials I used Speedokote. I used their primer, base, clear, filler, wax/grease remover, and a bunch of other supplies. All priced very competitively and as a novice was happy with quality.
I believe they have base/clear and single stage in a few colors and several different clear coats. I used their cheapest clear and would probably pay the small upcharge for one of their nicer clears.

No peeling, flaking, or rust bubbles. You'll probably have leftover materials, and you'll be able to make repairs whenever you want.
