What rivets to use?
I will probably be using rivets in some areas that will be checked by Mr IVA, has anybody here used rivets in exposed areas that have passed and what
size where they? Cheers.

Used 4mm stainless steel on the underside anywhere which may get wet - avoids the issue of electrolytic action and the are stronger than
'normal' pop rivets.
Mind you, you need strong wrists to put them in!!

Stainless steel is not a good idea.
"stainless steel; it is a very noble alloy meaning it is quite resistant to corrosion and has a high potential) and a mild steel (a very active
metal with lower potential). The mild steel will corrode in the presence of an electrolyte such as salt water"
Aluminium rivets will corrode before the steel chassis and will be easier to replace and should stop the chassis from rusting a little due to them
being a sacrificial anode.
Lots of interesting stuff on the net about galvanic corrosion.
Use a 3.2~4mm closed head aluminium rivet with a blob of pu to try and keep the water out.
But to answer your question I am not sure.
I read it as any protruding object over 5mm must have the correct radius and anything under 5mm needs to be blunted.
My boot cover and transmission tunnel are covered in large head 4mm rivets and I don’t really want to carpet / cover them.
