Surface rust in very awkward to reach places....

[zircon]

Hi Guys

Here is a picture of the inside of the rear wheel well in the boot of my 1993 MR2.



Although it looks orange it is apparently sound according to the place that repaired my sills and repainted my car last year. They said it was just on the surface and a good amount of screwdriver prodding seemed to confirm it was ok.

I want to sort it out properly before it is too late but access is pretty much non-existent.

Any ideas how to get it back to a good surface for paint?

Cheers

Soda blasting , there are plenty of companies who have a mobile service for localised areas like that!

Exactly what I was thinking mate - thanks!!!

They normally charge for a call out fee

So find any others you need doing and get them blasted at the same time

bilt hamber deox gel...soak it overnight and rinse /repeat until its clean

I would do the same. Remove as much surface rust as you can with a wire brush - the ones that come in a pack of 3 in Poundland are fine - then coat in 3mm of Deox gel, cover in clingfilm, rinse off after half a day, then repeat. Bilt Hamber Electric is a good primer for rust prevention.

Cheers everyone.

I would ideally like to do it myself so might give the Deox gel a go and then try soda if it doesn't work.
