I bought a painted spoiler which arrived on Friday. Being a red car the spoiler isn't quite as bright as the rest of the car so I was going to take my polishing machine too it, but worried the paint is too fresh, it was sprayed 10 days ago.

I would suggest that the panel will be the wrong colour, when it is freshly painted that is the brightest and clearest it will be. With paints (reds especially) each colour has a different variation so your red could have say 5 different variations from the manufacturer then on top of that the car will have suffered from oxidisation etc meaning painting edge to edge will result in what looks like a colour mis-match. My advice would be to go back to the workshop and ask them to try again or live with it but dont touch it with your machine polisher, for someone that doesnt have masses of experience with a machine polisher an intricate spoiler can be quite problematic.

I'd leave it another 10 days ... but what would worry me more is why isn't it as bright as the rest of the car?
Is it that it that the paint is a slightly wrong shade (in which case polishing won't help) or is it a bad/poor finish with the lacquer or is it a diy job using a cheap lacquer that's never going to buff up?

Most colours have AT LEAST one variant shade & for some I have formulations for a lot more.
Unless the paint used on the spoiler has been matched to the car - as in the painter has seen the car & checked the colour against swatches or eyematched the paint to the car - your chances of it being the right shade are very low.

My neighbour recently bought a pre-painted spoiler for a Rover from an on-line site. Colour code is correct, but its the wrong shade.

ETA. What make is your car & what is the colour code?

Thanks guys, here's some pics.

Car is a Honda S2000, paint code R510. It's a flat colour, so no laquer.

It looks a lot worse in the garage than when I roll the car out, in fact once the car is outside it almost looks acceptable. The car has just had a full paint correction which probably doesn't help.

I'm wondering if it's just to do with the angles, when I turn the spoiler face to be the same angle as the boot lid it doesn't look nearly as bad. Never had a red car before and wondering if this is normal.

To be fair the spoiler was an foreign ebay special so I knew I was taking a risk. £60 vs £450 Honda want for it. The quality and fit of the spoiler is exceptional. May get it resprayed locally, but worried it will just be the same.

Sorry to break the news to you but the car does have lacquer on it bud!

Yeah that is the wrong colour as I said, get it repainted! Where are you based?

Fair enough, I always thought non metailic colours didn't have lacquer, but when I think about it they must smile

Based in Aberdeen.

I might drop it off at a paintshop this, would rather not give them the car though, but that may be a bad idea.

I can understand why you would not want to leave the car with them but for them to have the best chance of getting the colour right id suggest leaving it there just stress to them in the nicest way that the car is your P+J, you should be ok smile Take your time finding the right place and dont go for the cheapest option all you will be right back where you started! Id suggest finding a workshop that use Dupont paints.

A lot of people think that solids are just base coat but this changed many moons ago!

Chances are around £100-150 so you will still be quids in vs Honda prices and even from Honda there is no guarantee the colour will be right, I had a customer with a grey/silver S2K that needed a new towing eye cover I had one ordered from Honda when it arrived it was a million miles off colour!

There is also the question of metamerism. This is the phenomenon where colours change according to the light source. Reds often suffer from this, but so can other colours. Seen under fluorescent or street lights, colours can appear a different shade. When checking colour shades, it should always be done in natural light or with a sun lamp. If you take the car to the bodyshop, make sure the colour check is done outside for the best match.

The colour variation can also be caused by the fact that the boot lid and the spoiler are two different substrates, metal and plastic as this also affects how the colour looks as the light reflects differently.

This shouldnt be a problem.

Spoke to the bodyshop Honda use in my area, they also all of Porsche's and Land Rover and have a very good reputation in the area. He costed the job at £220 as there are two shades of paint code R510, which I don't understand, surely a paint code should be unique. So basically they have to test both paints on swabs, then paint the spoiler. At that price I'll save up for a genuine Honda. Lesson learnt! Might try another spray shop, bound to be cheaper, but I'd trust these guys to do it properly. Although he couldn't gurantee the result which isn't reassuring.

Apologies Jules, I thought he had the boot done as well!

It can make a difference, best example being the old Audi A4 with 2 different plastics on the rear bumper that look different colours when painted together.

The thing with paint codes is that they signify the colour of the paint but not the batch.
The same model of car can be made at different factories around the world but they can't all use the same batch of paint.

Even in one factory do the bumpers and bodywork get sprayed with the same batch? And how large is a batch anyway? How many cars does a batch do?

Different batches often means one colour has varients

For Honda R510 in one paint system I have only one formulation, in another there are two shades and in a third just one but with a symbol that means the formula has been changed.
It's a common issue. Some very popular colours can have more than a dozen different formulations in one paint system, each shade being slightly different. As an example, Ford Frozen White - most common on Transit vans - I have over 10 different shades in just one paint system.
ETA As I said earlier, the best option would be to get the paint eyematched to the car by somone who knows what they are doing.
I get matches done by Sayers of Northampton. Min 1/2 litre & with matching charge around £50 plus the VAT. So far, I have not had to send one back.

I think someone else needs to come explain that paint codes have different variants.

It's impossible to buy an item which will match - your cars paint will have faded over the years remember.
You can either accept a variation in colour, get lucky, or have a large amount of it resprayed.

Right not read all the thread, is it would take too long to do so,

The Enzo we just painted had a colour code of PPG Rosso Corsa 322 .

So on a few different paint mixing schemes we had choice.

On the lechler mixing scheme with has one shade.

On the max Mayer scheme we had 3 shades

And the PPG mixing scheme we had a choice of 14 variants.

This is very common problem; it’s what one manufacture interprets a colour to another.

When we used the "max Meyer" paint mixing scheme with the aid of spectrophotometer, it came back with lotus red as the closest match then second was rosso corsa.

We then started the process of different spray out cars, neither was even close.

So then we done the spray process using 5 different mixing schemes using either the only shade choice or "standard shade option normally known as the "prime shade"

They are all different and easy to spot , as shown here








they look far worse in daylight then whats shown on the above photos

we ended up having to get an area paint rep in for spend around half a day playing with spectrophotometer and spray outs using the field colour variants to get the closest match .

I have seen some colours (my own car is one) to have only one shade option in the middle of the range paint materials suppliers and from one to another (my car being straight blue) being far more green in one make and far more blue in another .

It’s a mind field in truth.

And this was on straight colours, add in metallic and pearls to the equations then a new problem come into play.


If you want perfect match then either whole car / or large area then blend (which is still a trick of the eye and not fully prefect match)

We do also view colours slightly different, and you can train your eyes to see shades and contrasts.
