The effects of sunscreen on Volkswagen/Audi paintwork

A couple of years ago, my wife and I bought a brand new Volkswagen Golf.  We’d been happy with our previous VWs (a Mk2 and two Mk4 Golfs, a 2004 Polo and a 2005 Passat) so were more than happy to purchase a Mk5 Golf 1.9TDI Match (in Blue Graphite Metallic) as a family runaround.  Fast forward around a year and we were slightly less pleased with our purchase…

…The car had started to develop white marks on the paintwork.  Each time they were polished out, they came back.  Strangely, some of them looked like little handprints and, when I asked the dealer about them, they instantly recognised the problem.  “That’s sunscreen”, they said, “and it’s not covered by the warranty”.

Sunscreen?! Yep. It seems that the modern (water-based) paints are not as hard as the nitro-cellulose or isocyanate paints used on older cars and that they are susceptible to damage from titanium dioxide – an ingredient found in many sun protection products, including the sunscreen we had applied regularly to our young children.

With just a few thousand miles on the clock, I wasn’t taking no for an answer, but we decided to use a little of the motor industry’s sexism to our advantage too as, from this point on, the negotiations weren’t with me but with Mrs W. instead!  After escalating the issue to an appropriate level within the dealership, it was agreed that the car would go into the bodyshop and the offending panels would be machine polished, as a gesture of goodwill.  Even though the job took much longer than it should (most of the panels on the rear and sides of the car were affected – have you ever tried keeping toddlers from plastering their hands on a car?) they dealer was true to their word and the car was returned to us in as new condition. 

Damage caused by sunscreen coming into contact with car paintworkWhen I asked if this was a regular issue, Volkswagen told me that it wasn’t (although, later, an Audi dealer was a little more truthful, admitting that it happens a lot with modern VW-Audi paints and that the resolution is usually a machine polish – we also have friends with similar marks on their silver Bora).  Had it been necessary, I would have kept on pushing until the car was completely resprayed (I might have settled with a compromise agreement to pay for the materials but not the labour) but, as it happens, the problem seems to have been resolved, with just one small area of damage still visible.

We were lucky.  With just a few thousand miles on the clock, it was difficult for Volkswagen to suggest this was “normal”.  If the car had been used a little more, we might have been seeking legal advice to see if we were entitled to a return under the Sale of Goods Act (it is a family car after all, and blemishes as a result of contact with sunscreen might question its fitness for purpose) but I frankly wouldn’t fancy our chances at suing Nivea et al. for damages because their products don’t carry a warning that they may damage car paintwork!

Needless to say, these days we’re ultra-careful to wipe our childrens’ hands with wet wipes after applying sunscreen…

    Well, well, well! The rear door on my wife’s Astra had an unsightly hand print on it for a couple of years. I tried several times to get rid of it but to no effect.

    Only once she’d had a go at turning it into a Corsa and it spent a couple of weeks in the local bodyshop did it get rectified but I never found out how or what the source of the hand print was.

    Good find, Mark!

    Steve, Your comment about turning an Astra into a Corsa did make me chuckle :-) Unfortunately, the marks are returning on one of the doors… think it’s new marks rather than old ones coming back though… seems that, however hard you try, it’s difficult to keep small people’s hand prints off cars (and don’t get me started on the hairline scratch that’s appeared on the side of mine at about scooter handlebar height…)

    Hi there was in my dealership today with a similar problem and the damage to my car is now over five panels, some of the prints are quite large and there are also strange patches. The paint specialist who was female and frankly quite rude did not offer me any solution other than to pay VW to buff it out and they would not guarantee that it would not return. Any ideas?

    Hi Yvonne – all I can suggest it to try another dealership to see if they are more helpful. We were lucky that our car was nearly new and low mileage – if yours is a bit older you might struggle. Persistence (and being prepared to accept a reasonable offer, rather than holding out for a full respray!) would be the best I could recommend.

    Mark, If its Titanium Dioxide (TiO2), then practically anything that is white and man made these days contains TiO2, it is the generic white ‘colourant /pigment’ used to replace PbO, or lead oxide, previously used in paint to make it white. Which of course was banned along with lead in petrol, to be replaced with something much worse and carcinogenic to boot (benzene). There’s progress!

    So the ‘fitness for purpose’ issue will definitely arise over time.

    What happens with guano I wonder….

    Rog – thats interesting… I hadn’t realised that titanium dioxide was a generic white pigment. This post certainly seems to have picked up some interest though… and I notice that @VWwarranty is following me on Twitter now so I doubt that my case was an isolated incident.

    Have you tried using a) WD40 to remove the oil based content? b) A citrus degreaser? c) A polish (with an abrasive in it) as opposed to a wax/sealant – which sounds like what was used when you went to the dealer.
    Water based car paints have been around and used since the ’60′s. Some car paints are more complex than others but when polishing you really are just addressing the clearcoat layer above the paint. These clearcoats have different properties depending on colour of car/manufacturer.
    Take a look at detailingworld.com for some advice.

    Thanks for the tips Ed… I may well try some of those things on the remaining marks…

    We have had similar problems on most of the car panels on our 58 plate polo. I am also aware of a neighbour with a new VW Golf who has had the same issue. My wife took it to our local VW dealer who said they could try polish it out if we brough it back and left it with them. I did this and asked who would pay for the cost of it. They claimed to be totally unaware of it as an issue but said they will pick up the cost on this occasion. I asked about further occurances and they then said ” the 4 cars we have done the polish for before have not reported any re-occurance”. So much for being unaware of the issue. I can’t see that it won’t reoccur as hopefully next summer will mean more sunblock for the kids. Has anyone had any comment from VW Uk on this issue

    hi, just seen this searching via google we have a 60 plate vw fox that has developed these white marks over time, thing is they are delveloping now and it’s winter so the suntan lotion excuse doesnt wash with me, been in touch with the dealer who said he would take pictures and send them to vw, the salesman first blamed it mosture underneath the clear coat thing then there paint specialist brought out a folder which a couple of sheets with the same issue which vw blamed the use of hand lotion, mosturising cream or sun tan lotion, so we are waiting for them to take the pics and send off to vw, did you get this resolved after and did the marks come back after they machine polished it?

    Mark, the polishing didn’t entirely remove the marks – they came back after a while, but no-where near as bad, and not on all panels (i.e. partial success). I also have a similar mark on my Audi A4 – will be interesting to see if the lease company remarks on it when the car goes back at the end of its lease in the spring…

    Based on the comments here, it seems that there are many products that use titanium dioxide as a white pigment so, even though high-factor sunscreen is likely to be the main cultripit in my house (with two young kids), there could be other products (hand creams, etc.) that have a similar affect.

    Fergus (VW Polo Owner), I don’t believe that VW are unaware as my local Audi dealer also recognised the issue and they use the same paints! They might not want to recognise it though (entirely separate view!). Certainly nothing official that I’ve found from Volkswagen UK though…

    I’ve got the same problem on my toyota, only I can’t blame the kids as the handprints look like mine!. I’ve been thinking about the problem for a while, I think the best bet is electrostatic cleaning to actually pull the particles out of the paint.

    I wouldn’t have thought a solvent would work as the titanium dioxide bond is fairly strong, and washing them off would be hard as the size of the particles allows them to sit in the hollows of the paint, the natural asperities of the paint probably sit higher than the tio2 particles. (I think I’m right in saying that the particles are at the nanoscale which is why they sit in the troughs in the paint.)

    Anyway If I find an electrostatic cleaner, and am brave enough to try it on my car, I’ll come back and let you know how I got on.
