If you could get the stay clean enough then I think it would be worth a try, after all powder-coated alloy wheels seem to survive pretty well in harsher conditions.

The problem as I see it is that you'd have to blank off the screw holes as otherwise they'd end up undersized, and that would give a potential route for corrosion to get under the powder. Maybe Duralac could help here.


Or open the holes up slightly to allow for the powder coating.

If the powder coating will handle wheel bolt torques it should handle the tightening of the windscreen frame screws.

I asked a chap at an alloy wheel restoration company if he could coat my A pillars and he said that the metal was probably suitable but felt that it was too thin to take the heat of been baked and would warp or crack.

One coating that I like and often pondered on its suitability for my pillars is Niflor. I don’t know if anybody else is familiar with it? Not normally used as a cosmetic finish but a very specific industrial process that offers super wear, corrosion and friction resistance amongst other things. It’s hard and even repels water. It’s an electroless nickel PTFE composite coating with a colour very similar to my current satin silver/beige painted pillars. It’s very uniform and to the touch its silkier than a cashmere codpiece.

There is a powder coat company near here and I talked to them. They said they could do it but they couldn't guarantee the adhesion would be good everywhere which I took to mean no better than the current so decided not to. They quoted £50.

I subsequently did some research and it seems aluminium can be problem with powder coating with a number of possible chemical pre-treatements.

Wow. Both of my cashmere codpieces are really very silky wink . There's a real danger of this happening whenever I wear them... pantsdown

You could after cleaning them up, try one of the car 'wrapping' specialists

Loads of colours to choose from even 'carbon look' and Chrome are possible

This topic has given me some concern given that I spec'd the plain ally windscreen pillars instead of black finish ones. Was expecting polished but likely not protected with laquer given experience with M3W.



What I actually found on my near complete Roadster yesterday can be seen above. It looks like a powder coat in a very light grey which roughly matches the ally window frames of sidescreens. Just wonder if the no cost version have been finished like this for some time or if its a recent spec. change. Either way not complaining smile

That looks like the finish we got in Feb-14 as a standard.

Some very small bubbles are starting to form in the finish after 4 years.

Richard, it’s been that finish as standard for many years. Mines starting to bubble and has stained as well.....not quite what from!

There certainly was evidence of that but I think the greater issue is water/brine getting it at any point where the surface finish is chipped or cracked. As was said earlier the fixing locations are prime candidates for that. Our Kenwood mixer suffers the same problem.


Electrolytic corrosion as between steel fasteners and ally casting requires an electrolyte to form a miniature battery. Hence the salt water issue. Clean pure water on ally won't harm and will simply dull the surface a bit by adding to the normal layer of surface oxide. You can get a Teflon gel to insulate steel screws from the ally.
