Painting rear diffuser - questions

[Booth11]

Recently took car to bodyshop for an estimate for couple of things that need sorting.  As a repair to a dent will require painting, I've also asked for a price to have rear diffuser painted black.  Never liked that plasticky grey. Still waiting for price. 

However  assessor said that he'd need to check into whether it could be painted as apparently some diffusers emit something that can affect adherence of paint.  Anyone heard of this?  Or is he talking out of his ar*e?

Also would painting it affect warranty?   I know they'd have to prove that painting it had contributed to a failure (highly unlikely), but what about paintwork warranty?

Finally, what price would be reasonable for this job?

Thanks

I've never heard anything like that and have seen rear diffusers painted gloss black before now, so it can't cause too many issues.

can't see how it would affect the paintwork warranty either, but always best to enquire at the dealers.

They can be removed so can be replaced if it ever needed to be but as pryda says loads of people have had then painted gloss black or grey, if you do a search on here you'll find them.


I think he's talking out his @rse tbh!

I had my rear diffuser painted gloss black and also had the side skirts colour coded on a brand new car.
It should not affect the bodywork warranty.  At worse case, they won't cover the painted parts

I work for a company who paint plastic components for (mostly exterior) the automotive industry, should just need an adhesion promoter or special primer as the diffuser is like to be polyprop or PP.  This usually needs flaming (in the industry) or an adhesion promoter will make the paint stick....  Without these on polyprop there's a risk the paint will flake off, especially when put under the pressure of a jet washer.

what about vinyl wrap? I'm looking to have mine done is gloss carbon to look like this:

Don't know much about vinyl wraps, thing is if it doesn't work you haven't ruined your diffuser... you'd just be left where you started.

Thats the OSIR one, it's moulded carbon and megabucks! Looks the nuts though!

PS having to use an adhesion promoter or other primer shouldn't really have a great impact on the price, the cost for the adhesion promoter shouldn't really be any more than the basecoat... in my experience.

yeah it is. about 400 notes aren't they? there's a place by me that does good carbon wraps so hopefully it won't look much different. I just hope the wrap doesn't turn yellow under the heat
