What is the best way to remove surface rust from the inner wings and rear valance?

 

Wire Brush ? / Hand / Machine

 

Sand Blaster?

 

Something else I've not thought off?

 

Also does anyone recommend a rust treatment solution before I re-apply underseal?

 

Thanks in Advance

How rusty are they?

[dyshipfakta]

Jenolite is good stuff much better then Krust I think and cheaper too

Ultimately media blasting is best as this only removes the rust and not and of the surrounding metal. But normally with a mini surface rust is caused by the rot coming from the inside out.

[MrPUK]

All the Panels are solid ( Cannot tap them through ) , I would say it Looks worse than it is !!  but I do get what you are saying about the Rust though Sonikk4, I'm trying to see what I can salvage going forward..

 

I will have look at the Jenolite do you need clean the area first and then apply?

[MrPUK]

The Rear Valance by looks has been replaced at some point but was never correct weather sealed .. trying to avoid replacement if we can.. as the panel is solid, just looks a mess from underneath..

I use a wire brush either by hand or on a grinder to remove significant surface rust.

Just go careful with the brush on a grinder in case you do more harm than good.

For light rust I use some wet & dry.

Then as mentioned it can be neutralised with some rust converter.

 

Always worth considering the safety implications of a wire brush on the grinder & the dust created.

The thing with products like Jenolite is they don't actually remove the rust, they kind of seal it in....they say they 'convert' the rust to an inert or inactive material.........bla bla blaaaa........utter rubbish - they don't.  Used Jenoilte, Kurust, and a cheapy one from Toolstation...........all look like they've done something but 3 or so years down the line bubbles appear again.

 

Mechanical removal of rust is the only way to get rid of it......whether that is media blasting (certainly works but can be tricky in the areas you mentioned), sanding (B&D Power file is great for this!!!) or cutting out rust and welding new steel in (last resort!!!!)....that is the only true way to get rid.

 

If you want to get really into rust removal and resto....get the car dipped - that too removes all the rust.....and all the money from your bank account!!!!!!!!!

 

 

Best bet seeing as you don't really want to do any panel replacement (understandable) is to get rid of as much surface rust as possible mechanically - Get a Power file!!!! - then treat with one of the rust converters that don't actually work (might as well for the sake of a few quid), then paint with a zinc rich primer (available online or from Halfrauds), then top coat with whatever you want really (tougher the better) as some folks like an OEM painted finish, whereas some are happy to pile on the stone chip.  On top of all this, give a coat of Waxoil to protect against moisture.

Thanks Guys for taking the time to answer and give your experiences it really helps, all input is greatly appreciated - and all taken on-board.. including the safety concerns as well, I tend to use masks when I'm grinding + googles

Strip it to gain access to areas and get it blasted. Nice dose of deoxidene and coat of zinc primer. Paint and dose with Tectyl or similar. Can't do much more than that without dipping it.
