Thanks for all the advice folks. In the end I have plumped for zinc plated mild steel rivnuts, and stainless fasteners. I will use the wet insertion method that has been suggested, then paint around them and they will also get coated in dynax UC (like most of the rest of the car!)

 

Cheers

Stainless screws in mild steel Rivnuts can corrode and very effectively seize solid. I've had several in my grille become impossible to remove and need drilling out. I wouldn't use that combination again, I just have regular cheap cheese headed screws in there now and it's fine.

For galvanic corrosion to occur you still need an electrolyte to allow the file of ions. So go hard woth paint and protection and you should be able to stave it off for a while.

Thanks guys. Might just opt for the plain zinc coated steel screws as well then Dan. I guess the point is that I will be removing these fairly regularly for cleaning etc, so I can always just replace the screws if they are starting to get grubby.

Has anyone tried to apply a rivnut on a painted panel to secure wheels arches? Any damage to the paint? like cracks?

some times yes some times no.

 

it all depends on the quality of the surface and paint and the rivnuts used.

So, there is a strong possibility.. my question is because of the rear wheel arches.. they are currently mounted with normal rivts, but i would like to have the possibility to take them out whenever i wanted..

if there is any filler then you are more likely to have problems. alloy rivnuts set at a lower pressure so less likely to result in damage. BUT depending on where your arch is positioned I seem to remember that there is not much space between the side and the inner arch which can lea to fitting issues.

Thank you very much for the honest answer.. Yes, space might also be a problem.. I'm starting to wonder if i should continue using normal rivits.. :)

Yes I've done mine ... the catch is that you will need to drill the panel to suit the Rivnut you intend to use ... which will be a bigger diameter than the original rivet.

 

It's therefore necessary to re-seal the metal within the hole to avoid corrosion. Other than that the Rivnut is unlikely to cause any damage to the paint when you clamp it tight with the Rivnut tool.

Rivnuts are brilliant for arches- as above, the issue you may come across is on the rear where the inner wheel arch meets the rear quarter panel. I 'solved' this by putting a punch in the hole for the rivnut and tapping some clearance in.
