Hey guys, I'm looking for some advice on what to do for the next step of my 240z project. I have the car stripped down to a rolling shell with the engine bay primered and the underside undercoated already. I'm debating between sanding down the exterior and interior to factory primer, repairing any trouble spots in the process, and then shooting paint OR having the interior and exterior media blasting with fine crushed glass (hopefully less likely to warp) and then shooting paint. The factory paint looks okay. There are few spots that have cracked and are peeling but overall it's not bad. Some spots will have to come down to bare metal anyway for repairing. Which route do you guys think I should take? I have a large compressor and the tools to do the sanding. Media blasting would make the following easier, though: One big issue is rust. There are several rust spots that I'm concerned about and am not sure what to do about. There's rust around the inside perimeter of the roof. There's rust inside the passenger and driver side vent plenums that run to the engine bay. There's rust inside the cowl area. There's some rust in the rockers (not too bad) and the dog legs are pretty rusty. I boroscoped most of these places and have some pictures below. The worst of it all is in the dog legs. In the other spots there rest seems to be bubbling a little but mostly on the surface -- some pitting. I'lllet the pictures do the talking. The car: Dog legs: I will most likely be replacing these. Inside the rear wheel-well area above the dog legs: Around the the inner perimeter of the roof: It's rusted most of the way around and the rust goes into the recessed area all the way around. This is perhaps only surface rust and would come off with a wire wheel, but the issue is accessing this area. This is where blasting would be nice and this is one of my biggest concern areas. Inside the driver and passenger vent air plenums: Some other rust around the hatch sill: What do you guys think I should do about the rust areas? Should I get everything blasted as best they can do then seal it? Should I sand/wire brush everything I can and treat it with some ospho or other converter then seal it and use cavity wax? I have these products on hand. I've already put a lot of money into this project so I'm all in and want this to be near show quality and last a long time. I don't know if it's worth it to split the seams on some of that rust or not. How hard is it to remove the roof? I did my own floor pans, battery box, and frame rails.

Hello everyone on HybridZ! First a quick introduction, as this is my first post here on the forums. About a year ago, I bought a 1971 240Z which I bought from a gentleman Tecumseh, Oklahoma (right outside of Oklahoma City). I don't know much about the car's history aside from the fact that it sat at the gentleman's house since about 2008 because he thought that the engine was blown. Well long story short, the carbs were way out of tune and the distributor was turned about 180 degrees. Now a year or so later I haven't been able to get much work done, however I am in the process of stripping down the whole car, bagging and tagging everything. Being that the car will hopefully be completely stripped of all of its parts soon, I am looking into fixing the rust that exists on the car. The floor pans are long gone as well as the entirety of the passenger footwell all the way up under the cowl, just on the passenger side fortunately. The other hotspots per se are the driver's side a pillar which has a large rust hole, and a few other spots here and there. I am wanting to remove all of the rust that I can in order to ensure that my long-neglected Z doesn't have rust issues in the future. I plan on having it media blasted and epoxy primered (to prevent rust until I can have it painted), I was quoted about $1500 for the media blasting and primer work. I plan on replacing the floor pans, the frame rails, the rust hole on the a pillar, battery tray, etc. Now for my actual question, thank you for staying by the way. My main question is, in what order should I go upon repairing the rust and body flaws? Before or after the media blasting and primer? I've got a lot of work on my hands and I appreciate any advice that you've got. Thanks!
