Sorry to hear this - I would expect the dealership to fall over themselves to put it right as this should have been picked up as part of the PDI process or the secondary check at handover if the vehicle has been stored for a while.
At the very least you should expect an “as new” reparation along with a gesture for the inconvenience / loss of use which would usually come in the form of complimentary servicing or similar (which you may be loathe to accept based on this experience of the dealer).
Hi urowho… Sorry to read about the issues your having with your new MX-5… All of us here just want to experience the positive, the fun, the driving and the whole MX-5 experience - Those who have never driven one don’t know what they’re missing.
Regarding the issues specifically.
Bird s-h1t is acidic and the longer it remains on paint the worse the damage… It could be flatted out but is likely to return as it’s corrosive characters remain… I can’t imagine a satisfactory repair without it being stripped and repainted - not something I’d be keen on in what’s supposed to be my new “Pride & Joy” If they had another new bonnet, same colour and perfect, I’d request it being changed.
The i-eloop, internal courtesy lights, have a browse through the Owners Manual or go back again to the dealership - It is their responsibility to explain these features, how they operate etc during the Customer Handover Process.
The water splash marks under the bonnet are commonplace in new car dealer prep… (3rd Party Contract Valeters!) It will have had a quick pressure wash and be left to dry naturally… If it was me, I’d do a detail myself at a later date after other issues have been resolved…
Hope this helps…

A dealer won’t stock or have access to a pre painted bonnet, that’s not how it works.
The only way to get a factory painted finish would be to swap it with another car and touch in the mounting bolts after it’s fitted.
Given it’s colour I would suggest it will be extremely difficult to get a perfect match from all angles and in all lights unless the wing tops and front bumper are ‘blended’, although the chances are the actual paint quality and finish would be better than oe.
Mazda’s clear coat/lacquer is incredibly, ridiculously soft, as my wife’s just found out after brushing some hedgerow (mainly nettles) in her brand new £40K CX5. Even the dogs squeezing down the side results in scratches. Hmmm.
Rhodesian (Zimbawean ?) Ridgebacks? 
I had two ■■■■■ Rhodesian Ridgbacks 30 years ago now. Awsome dogs, another life.
No, GSP’s (sorry German short haired pointers)

Hi Overdrive… Sorry I wasn’t clear in my post. That’s what I meant to say - If they had another new car of the same colour in stock, they could swap the bonnets, even if that only moves the problem on to the next car…!
Rob
At least that will give them some time to get a fresh one in and make an existing customer happy, but if its from an existing car, it would also have to be new as they do damage easily… Perhaps a difficult ask, but it needs resolving.
That does happen sometimes.
A friend of mine once bought a black pre reg motorcycle, and when the docs turned up it was supposed to be red.
Turns out the dealer had a lesser model in black and just swapped the tank/fairing etc. (Bodywork was the same on both)
At least he was honest about the cock up.
Just take it right back to them and have them sort it.
Why you’re even considering anything less is not even in the thinking…
I certainly agree with that in principle, but you can see how it might go. They’ll repaint it, it won’t be right, they’ll paint it again and so on, and there will always be reason to think it’s not quite right. Even an unrepaired one tends to look a different colour on the bumper and in very directional light from panel to panel either because of what it’s painted on to or the orientation of the flakes.
I tend to feel relieved when a new car gets a slight mark, as long as it’s nothing serious or noticeable. It’s no longer ‘perfect’ so subsequent blemishes don’t matter so much.
It’s not uncommon for new cars to have had bodywork rectification before they even reach the dealer. I once got a new Golf on which one of the front wings was slightly misaligned and had a distinct pink tinge. I know it wasn’t done at the dealer because I saw it come on a transporter with other new stock. On that occasion I just advised my employer (it was a company car) and put it to the back of my mind.
I don’t think I’ve ever bought a car without a paint defect until I was fortunate to be able to buy more premium makes. My NC Venture had a very slight 3" scratch on the n/s wing which had been quite professionally touched in probably at the factory I have no idea how they did it. It was only noticeable to somebody as fastidious as me and returning it to the dealer would have only ended up with something far more noticeable. There is always the hairdryer trick, heat the mark with a hairdryer and sometimes the surface of the paint heals itself. I tried this on a Golf R after Gull ■■■■ had been on it for over a week in the baking sun and it did improve the paint surface, although still there, it was less noticeable. Unfortunately all modern carpaint is far less durable than it used to be but apparently it’s something to do with saving the planet.
“apparently it’s something to do with saving the planet”
Yes, very much so, The paints used now contain far less Volatile Organic Compounds - VOC - some of which cause respiratory problems. cancers etc. and also attack the ozone layer in the atmosphere. Plenty of info. on the internet.
I believe that when we buy new cars, different people have different standards. Some may give their new car a brief look over when taking delivery, others will give it the “Fine Toothed Comb Out” treatment…!
For some it’s no more than a mode of transport and to others it’s their potential Pride-And-Joy…
Dealers also sub-contract the valeting out to a third party, and in most cases do largely a satisfactory job in sometimes what is a large turnover demanding environment.
The problem I have with the OP’s paint issue is that it would undermine my confidence in the car, it being brand new and already repaired… I understand this is a state-of-mind issue, and other’s would be less concerned.
I got my MX-5 at just under 2 years old, viewed and took delivery on a cloudy day… Few stone chips here and there, didn’t notice some light surface scratching until I got it home and the sun came out a day or two later… Just concluded it is a used car, been kept very clean, if not “detailed”, and that’s how I like to keep it - Not perfect paint, but very clean and well polished…
TBH am glad it wasn’t new so expectations can be less…

Water based paint isn’t it these days, so very soft and damages easily.
Worth getting some ceramic coating on it to give it another layer of protection against light scratching and bird poo.
My company car had loads of bird poo marks on it (pre-reg sat on a Lowestoft dealers forecourt for 6 months…). I tried polishing out one of the 6 marks and got nowhere with it, I then found out about the hair drier trick and got rid of the other 5. The only one that never shifted fully was the one I’d attempted to polish out but that may have been a coincidence I guess!
Remember that what has actually happened is the poo has sat on the clearcoat and as the clearcoat has changed temperature said poo has caused the clearcoat to expand and contract at different rates, hence the now textured appearance. If you can get the clearcoat hot enough it should soften and find its own level.
This is why new cars are so susceptible to the problem as that fresh coat of clear may be dry but it will take months to fully harden. This is also why we think all car dealers wash the brand new motors with a grit filled brillo pad… which is only partly true, that super soft clear is also why you get swirls thrown in free of charge.
Different story on cars without a clearcoat (like my poor NA) where you get actual cracking and crazing of the paint. That is less common but also much harder to fix when it does happen.
I’d be careful with heating your clear coat you may make it worse
Better to get a detailer to carefully machine polish the damage out, they can use a depth guage to manage how much clear they remove.
Then get a ceramic coating on it, bird poo can’t burn through that.
Did anyone spot the link to the Autoglym product that I posted early on in this thread?
It’s designed to do exactly what you’re talking about.
Might be worth considering?
I hadn’t so thanks for that. Certainly worth a go in my opinion. 
Was hopefully buying a new CX5 in red metallic in the coming weeks but what I’m reading about the paint is making me a tad nervous.
