Rustbusters - they advertise in the classic car press. Quite a trek from you for the in-house service as they are in Spalding, Lincolnshire. their 'archguard' service would probably stop Bongo rear wheel arches disintegrating :?
They did an MG for me last autumn, when I got it back it was so thorough a job that waxoil was leaking out of the door handles. Not a problem on that vehicle but you wouldn't want it on the velour bit of Bongo door cards.
Also gave the car a nice 1970s- style freshly undersealed smell!
They also sell the products they use for DIY.

Good morning
I've used the dinitrol products on the mx5s and the bus and find them good. Rust converter , cavity wax and underbody sealer . I find it dries in the surface but stays soft underneath so chips from the road don't crack it .
Remember that the most important thing is prepping the surface Ie getting rid of all rust either by cutting out and replacing with solid steel and / or using the converter .aldo make sure the surface is clean and dry , and undercarriage power wash works well here , you don't want to be sealing in dirt and moisture !
It will only take an hour to apply the sealers but might take a few days to prep for it :shock:
Best of luck with it and keep us informed as to your progress

I did my JAL V6Bongo my self .. but decided to get my V6 Alphard properly done by Krown Rust proofers (Tipton) ....

A brilliant service/job done in a nice clean workshop (actualy at the rear of a JDM importer) .. I sat .. waited and watched while the job was done .. the five doors .. bonnet 'braces' ...

All the wheel / under body plastics were removed then a full hour doing the sills ... every mm of the under body/cavities etc: ... in fact, every nook and cranny was thoroughly injected using various probes .

It took a full three hours to do all the "wax oiling" .. then finally a full body car wash .. I am more than pleased in having such a Profesional job done ...

My only 'negative' observations, where the amount of surplus 'oil' seeping out of the doors .. sills .. cavities etc: for several days .. (not good if you have block paving or a posh drive) .. and they spray all the disc brake calipers/splash guards/springs etc:.. for half an hour or so .. your heart stops quicker than the bus ..!!

Dunno if they are a national company (Google) .. I have no connection what ever with the (Canadian) company .. I mentioned I am on Bongo /Toyota Forums and got a 5% discount off the £320 cost ..
