white corrosion on tool boxes of RFSV

[Ford Blitz]

Due to what I can only assume is a lousy paint job done by defence I am dealing with a white powdery corrosion under the paint on the storage boxes in the back of my RFSV. I want to do a proper job on repair which will involve stripping the paint back and treating the corrosion. It will also involve the temporary removal of the webbing around the storage area. I am looking for any advice on the treatment and where I would source replacement rivets for the webbing.
Should I consider soda blasting the surface?
Any advice would be welcome

I have encountered the same issue with the bins and internal racking on my RFSV.

The interior of the bins are both having the same problem now too.

The best way I have tried is to scrape or gerni off as much of the paint as possible, then hit with straight white vinegar applied with a dustpan brush. Leave the vinegar to dry then wash the treated area well with plain water to neutralise the acid in the vinegar. This all gets rid of the powdery corrosion. 

Once dry, hit with cold gal spray paint straight over the area as an undercoat - I did two coats and allowed to dry before spraying with Protec Camouflage Green another two coats. I'll be doing the same with the interior of the bins relatively soon. I had to do the steel areas on the brushbar too for the same reason.

Able Industries did a terrible job when prepping the RFSV parts for galvanising or painting.

Thanks for the advice. did you have to remove any of the webbing to get at the surface around the racking?

The previous owner of my RFSV chopped out the racking with an angle grinder, so all of the footman loops and the webbing are detached and are in the parts bin with the chopped racking pieces until I get around to rebuilding and reconstructing the racking.

If it was all still intact, I would have removed the webbing before treating the corrosion to make repainting easier. 

The correct rivets for the footman loops are listed in the RFSV (modified) RPS, but unless you're rivet-counting, I'd just use any stainless steel rivets which will fit. The originals were aluminium, but since the racking is steel, you'll have fewer dissimilar metals problems with stainless steel rivets.

excuse my ignorance but where do I find the RFSV (modified) RPS to reference

The AFM Safety website (https://afmsafety.com.au) has RPS, Electrical Mechanical Engineering Instructions (repair manuals), Data Summaries, Technical Descriptions, etc. for all variants bar the SRV-SF and LRPV for free download. Here's the direct link for the RPS for the RFSV - https://afmsafety.com.au/wp-content/uploads/2018/10/RPS-02290-LandRover-110-4x4-RFSV.pdf

The RFSV Repair Parts Scale has been published in book form too. https://www.amazon.com.au/Repair-Parts-Surveillance-Lightweight-Storage/dp/1925907244
