Decided to clean up the car a bit. See what I need to do.
I cant decide the best way to remove the paint in here. Any suggestions welcome. I'm leaning towards taking it to a master blaster. Sand or Soda....?? Any experience with soda blasting pros and cons also welcome.
Sorry, I've only just seen this. I have previous personal experience with sand blasting, and I've just looked into soda blasting for my next project, as all of the outer panels on the range rover classic are an aluminium alloy, birmabright.
So the main pros of soda appear to be that it's great for paint removal without generating any heat distortion on thin panels or surface damage to soft metals like aluminium or plastics. It also won't affect any chrome, rubber trim or glass left in situ. It leaves a protective coating on the surface, that will give a few weeks of protection in dry storage before you need to prime. It's safer to use and easier to clean up than sand.
Cons, are it won't remove any seam sealers, decent fillers or heavy rust - you'll need a harder medium for this. It's residue coating needs to be washed off before priming. It creates a lot of dust, although I can't believe it's any worse than the mess sand blasting creates.

It's also one time use only, as it works by exploding on impact, however, personally when I've sand blasted it's created so much mess with the aggregate, that you have to be committed to strain it out and reuse. It needs a higher pressure and greater flow from your compressor.
If you are having it blasted by someone else, most of the pros/cons won't make a difference, apart from soda will be a bit more expensive. Although the soda will be better for the thin panels used on the 500.
Given where you need to clean up, and that it's now that it's all enclosed in again with the front panel and wings, I'd say that it will be easier to have it blasted than stripping.
I'm planning to buy a soda blaster and do it myself, as in addition to bodywork, I want to use it on the top tailgate with glass in situ, the diff and axle housings, as it doesn't damage the flange facings, and to clean up the engine, gearbox and transfer box. So for me it makes sense to buy a unit.
I hope this helps.
